The area lies opposite the bottom wall of the first transportation compartment on the bottom side in the direction of gravity of the first screw element and opposite sidewalls of the first transportation compartment on both transverse sides orthogonal to the direction of the axis of rotation of the first screw element. In this area toner concentration of the transported developer is determined using a toner concentration sensor. The clamping wall comes into contact with developer on the top in the direction of gravity, with the developer moving from the bottom to the top side in the direction of gravity in accordance with rotation of the first screw element and presses the developer down in the direction of gravity.

EFFECT: more accurate toner concentration detection.

SUBSTANCE: in development cartridge contact plate of electrode element is arranged with the possibility of contact with contact site of development shift within the limits of projection plane, when slave binding part is projected in the first direction. The first axial line, which is axis of developing roll shaft, and the second axial line, which is axis of inlet toothed wheel, are arranged parallel and equidistantly in fore and aft direction. Part of contact plate is arranged on the second axial line. The first line that connects axis, around which inlet toothed gear rotates, and shaft of developing roll, and the second line that connects contact plate and shaft of developing roll are arranged parallel to each other. Distance between the first axial line and the second axial line is equal to the distance between the first axial line and contact plate.

EFFECT: stable supply of power to shaft of developing roll, even when motive force is sent directly from master binging part of device for images generation to slave binding part of development cartridge.

SUBSTANCE: cartridge for supplying developer is made with possibility of detachable installation into the main unit of the electrophotographic image formation device. The primary colour cartridge includes: an electrophotographic photosensitive drum; a developer roller designed for developing an electrostatic latent image formed on the electrophotographic photosensitive drum, a valve section of the receiving side which moves between the position for allowed reception of developer for opening developer reception holes, a moving section of the receiving side which moves for interrelated movement of the valve section of the receiving side between the position for allowed reception of developer and the position for prohibited reception of the developer. The moving section of the receiving side includes a working section of the receiving side which occupies the working position when the valve section of the receiving side is in the position for allowed reception of the developer, a control element designed for controlling movement of the moving section of the receiving side when the working section of the receiving side is in the working position. The cartridge for supplying developer also includes a developer holding section for the source side, a valve section for the source side which moves between the position for allowed supply of developer for opening holes for feeding the developer and the position for prohibited supply of the developer for closing holes for feeding the developer and a moving section for the source side. The moving section of the source side moves when the cartridge for supplying developer enters the main unit of the device in a position where the primary colour cartridge is installed in the main unit of the device for interrelated movement of the valve section for the source side from the position for prohibited supply of developer to the position for allowed supply of developer as a result of linkage with the working section of the receiving side of the moving section of the receiving side, whose movement is controlled by the control element in a state in which the working section of the receiving side lies in the working position.

EFFECT: design of a cartridge for supplying developer, a primary colour cartridge and an electrophotographic image formation device in which when the cartridge for supplying developer is extracted from the main unit of the device in a position where both the primary colour cartridge and the cartridge for supplying developer are installed in the main unit of the electrophotographic image formation device, loss of developer through holes for feeding the developer or through holes for receiving the developer can be prevented.

SUBSTANCE: proposed is a developer transportation device which has a developer transportation unit and a toner concentration detection unit which can detect concentration of toner in the developer by getting into contact with the developer or a toner concentration sensor or the wall of the developer transportation unit. The average maximum value of the force pressing the developer to the surface of the sensor of the toner concentration detection unit or to the wall of the developer transportation unit ranges from 9.8×15 N/m2 to 9.8×100 N/m2. Proposed also is an image processing unit which has a latent image holding unit and a developing device which has a developer transportation device and a developer holding unit; an image formation device which has a latent image holding unit and a developing device.

EFFECT: more accurate detection of toner concentration.
