PROCESS CARTRIDGE AND IMAGING DEVICE Russian patent published in 2021 - IPC G03G21/18 

FIELD: image formation.

SUBSTANCE: invention relates to a technological cartridge in which there is an electrophotographic photosensitive drum and a developing roll acting on an electrophotographic photosensitive drum, made with the possibility of connecting to each other and moving away from each other, and to an electrophotographic imaging device in which such a technological cartridge is installed with the possibility of extraction. The process cartridge is removable and installed in the main unit of the electrophotographic imaging device. In this case, the main assembly contains an opening and a door made with the possibility of moving between the closed position for closing the hole and the open position for opening the hole, the first force element made with the possibility of moving together with the movement of the door from the open position to the closed position, and the second force element made with the possibility of being moved by the actuating force from the drive. In this case, the cartridge contains an electrophotographic photosensitive drum, a developing roll for developing an electrostatic latent image formed on an electrophotographic photosensitive drum, a drum block containing an electrophotographic photosensitive drum, a developing block containing a developing roll and made to move relative to the drum block so that the developing roll can move between the contact position, in which the developing roll is in contact with the electrophotographic photosensitive drum, and the withdrawn position in which the developing roll is withdrawn from the electrophotographic photosensitive drum, and the force-receiving device containing the first force-receiving section for receiving the force from the first force-applying element when the door moves from the open position to the closed position in the state when the process cartridge is installed in the main unit of the device through the hole, and the second force-receiving section, made with the possibility of moving from the waiting position by the movement of the first force-receiving element under the influence of the force received from the first force-applying element, in which the second force-receiving section takes a protruding position to receive force from the second force-applying element to move the developing block from the contact position to the allotted position, while the protruding position is located above the waiting position.

EFFECT: creation of a diminished technological cartridge, in which the electrophotographic photosensitive drum and the developing roll are made with possibility of contact with each other and removal from each other.
