Node 160 receiving drive force includes a connecting gear 161 mounted rotatably in the housing 110 manifesting device, and the drive gear 162 showing the roll which engages with the connecting gear 161.

In addition, the main body 10 of the device imaging contains the transmission gear 81 for transmitting drive force for manifesting device 100K. When you install the developer machine 100K in the main body 10, the connecting gear 161 displaying device 100K is engaged with the transmission gear 81, as shown in figure 4. Transmission gear 81 is driven by a motor (not shown)mounted in the main casing 10. The connecting gear 161, rotating in mesh with the transmission gear 81, and transmits drive force to the drive gear 162 to rotate the drive roller 140. In addition, the connecting gear 161 transmits driving force to the feed roller 130 (figure 2) and a mixing element 150 (figure 2), thereby to drive these components in rotation.

On node 170 receiving supply of electric power required for electrification showing the roller 140, the feed roller 130, or restrictive element 111. Therefore, the node 170 dietary intake is located on the other side of the anterior end showing the device 100K.

When the visible image is transferred from photosensitive media 40 on the intermediate transport belt 51, a second transfer roller 53 is allocated from the intermediate transfer belt 51. Alternatively, after the image from the photosensitive medium 40 will be completely transferred to the intermediate transport belt 51, a second transfer roller 53 is brought into contact with the intermediate transfer belt 51 with a predetermined pressure. When you have reached the contact between the second transport roller 53 and the intermediate transfer belt 51, the visible image is transferred from the intermediate transfer belt 51 on the printed media.

The locking device 60 includes a heating roller 61, including the source of heat and the pressure roller 62, to ascertain the tion opposite to the heating roll 61. When the printing medium passes between the heating roller 61 and the pressure roller 62, an image is recorded on a printing medium by heat transmitted from the heating roll 61 and the pressure created by the heating roller 61 and the pressure roller 62.

The device 70 print media, including bringing the roller 71 and the supporting roller 72, and outputs the print media that has passed through the fixing device 60 of the main body 10.

The following is a brief description of the above-described device imaging. At the beginning of the print operation, the surface of the photosensitive medium 40 is uniformly electrified electrifiable roller 42. On electrosound the surface of the photosensitive medium 40, a laser scanning device 30 projects light corresponding to image information in any one color, such as yellow light. Accordingly, the photosensitive medium 40 is formed electrostatic latent image corresponding to yellow color.

Further, by showing Valka 140 manifesting device 100Y for yellow is attached showing the impact. Accordingly, the yellow developer is attached to the electrostatic latent image, thereby forming on a photosensitive media 40 yellow visible image is about color. This visible image is transferred onto the intermediate transport belt 51 through the first transport roller 52.

After migration to the yellow image for one page, a laser scanning device 30 is projected on the photosensitive medium 40 light corresponding to image information of another color, for example, image information of Magenta. The device 100M manifestations purple color to produce a visible image, feeding Magenta developer to the electrostatic latent image. Visible Magenta image formed on the photosensitive medium 40 is transferred onto the intermediate transport belt 51 through the first transport roller 52. At this time, the Magenta image has been superimposed on the yellow image, which was transferred earlier.

By repeating the same processes for blue and black colors on the intermediate transport belt 51 is formed full-color image in which yellow, Magenta, cyan, and black images are superimposed on each other. Full color image is transferred onto the printing medium when the printing medium passes between the intermediate transfer belt 51 and the second transport roller 53. Then, the print medium passes through the fixing device 60 and the output device 70, thereby leaving the core the main body 10.

During the above-described printing process, the developers stored in the respective manifesting devices 100K, 100C, 100M and 100Y, are consumed, and the service life of such parts as manifesting roller 140 and the feed roller 130, is gradually consumed. Therefore, the user needs to know various information about manifesting devices 100K, 100C, 100M and 100Y so, in order to replace them.

As shown in figures 1 to 4, each of the developing devices 100K, 100C, 100M and 100Y includes a storage device 180 for storing various information about the use. For example, the storage unit 180 may store information about the background of the individual operations of the developing devices 100K, 100C, 100M and 100Y, about the remaining quantity of the developer and the remaining service life of components, such as displaying roller 140 and the feed roller 130.

The storage device 180 contains terminals 181 for electrical connection with a power source located in the main body 10, for example, the circuit Board 90. The main body 10 includes a point 13 of the contact terminals 181. Point 13 of the contact terminals is formed on the cover 11 of the main body, which is located at the rear part of the developing devices 100K, 100C, 100M and 100Y, and electrically connected to the circuit Board 90 wiring harness (not shown). Point 13 of the contact terminals may have a predetermined elastic is here to maintain contact with the terminals 181.

Next, an example will be described storage device 180 manifesting device 100K black. However, this description equally applies to storage devices 180 manifesting devices 100C, 100M and 100Y other colors.

Figure 5 shows a back side view showing the device according to the variant of a common concept, consistent with the present invention. As shown in figure 1-5, the storage device 180 is located on the rear side showing the device 100K on the direction And install the developer machine 100K in the main body 10. Terminals 181 of the storage device 180 pass out through the rear end 101 displaying device 100K.

When the storage device 180 is located so it can be removed from the locking device 160, the photosensitive media 40 and showing the roller 140, as shown in figure 2. As a result, it is possible to prevent damage to the storage device 180 warmth as pollution terminals 181 scattered developer. In addition, since the terminals 181 of the storage device 180 are located on the rear side showing the device 100K, reduces the influence of other components. Therefore, terminals 181 are not damaged when inserting and removing displaying device 100K from the main body 10.

In addition, as the CSP is shown in figure 4 and 5, the position of the mass storage device 180 is shifted to one side from the middle With the width of the displaying device 100K. More specifically, the storage device 180 is displaced to the left in figure 4 and 5 so that the terminals 181 are located relatively closer to the node 170 dietary intake than to the node 160 receiving drive force.

When the storage device 180, thus, is located in relative distance from node 160 receiving drive force, the memory device 100 is not very affected by vibrations caused by the transmission of drive force from the main body 10 to the node 160 receiving drive force. Accordingly, the connection between the terminals 181 and the contact points 13 can be kept stable.

In addition, when placing the storage device 180 relatively close to the node 170 of the reception power, the position of the contact points 13 on the cover 11 of the main body is shifted to a printed circuit Board 890. Therefore, the length of the harness connecting the contact point 13 can be reduced. This reduces the cost of the harness, and also reduces the influence of electromagnetic waves generated around the harness.

As shown in figure 5, more specifically, terminals 181 of the storage device 180 contains terminals from the first to the fourth a, 181b, s, 181d, located in the direction of the width W manifesting device 100K.

The first terminal a javljaetsja for data exchange for exchanging information with a control device (not shown), located in the main body 10 of the device imaging. This control device (not shown) of the device imaging through the first terminal a reads necessary information from the storage device or writes to a storage device for new information.

The second terminal 181b is a ground terminal for grounding the storage device 180. A third terminal C is a power terminal for supplying power to the storage device 180. The fourth terminal 181d is a clock terminal for transmitting clock signals to the memory device 180.

For example, among the four terminals a, 181b, s, 181d first terminal a is located most remotely from the host 160 receiving drive force manifesting device 100K. As shown in figure 4, when the node 160 receiving drive force is on the right side shows the device 100K, the first terminal a is in the leftmost position among these four terminals.

The reason for placing the first terminal a as far as possible from node 160 receiving drive force is the desire to limit errors in data transmission caused by vibrations emanating from node 160 receiving drive force.

Among the four terminals a, 181b, s, 181d second terminal 181b, for example, may be closest to the node 160 receiving privode what about the effort. That is, when the node 160 receiving drive force is on the right side shows the device 100K, as shown in figure 4, the second terminal 181b is in the rightmost position among these four terminals.

The second terminal 181b, which is the ground terminal is in contact with the contact point 13 on the cover 11 of the main body and does not receive and/or transmit any information or signals. Therefore, although the second terminal 181b most subject to vibration, as it is located closest to the node 160 receiving drive force, the chances of errors due to bad connections are reduced.

However, given that the vibration is the biggest influence on the second terminal 181b, it can be made larger in area than the other terminals a, C and 181d.

As follows from the above description, showing the device in various variants of a common concept, consistent with the present invention, damage and contamination of a storage device can be prevented by placing the storage device on the rear end of the developer machine.

In addition, the storage device is located in a position that is less susceptible to vibrations transmitted from the node receiving drive force manifesting device. Also, the terminals of the storage device are in accordance with the plans provisions taking into account the respective functions of each terminal so that to mistakes caused by poor connection, can be minimized.

According to different variants of a common concept, consistent with the present invention, since the contact point terminals connected with the storage device, are located closer to the circuit Board that supplies power to manifest the device, the length of the harness connecting the contact points of the printed circuit Board can be reduced. This reduces the cost of the harness and is limited to the harmful effects of electromagnetic fields generated around the harness.

Although the above described device for the formation of color images having many developing devices, the General concept that meets the present invention is not limited to a device for the formation of color images. That is the General concept that meets the present invention is also applicable to the device forming monochrome images with a single developing device.
