CARTRIDGE, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC IMAGING DEVICE Russian patent published in 2021 - IPC G03G15/00 

FIELD: imaging devices.

SUBSTANCE: group of inventions relates to cartridges used in the image forming devices of the electrophotographic type. The essence - the cartridge contains a photosensitive drum; a developing roller made with a capability to develop a hidden image formed on the photosensitive drum; a movable lever; an input drive member to receive a driving force outside a process cartridge for rotating the developing roller. The input drive member is designed to move in response to the movement of the movable lever between the first position and the second position, in which the input element of the drive is withdrawn from the first position. And when the cartridge is oriented so that the photosensitive drum and the developing roller are located on the bottom side of process cartridge, the end of the lever is located on the underside of process cartridge, and the axis of the input drive member is located above the axis of the above-mentioned developing roller and the axis of the photosensitive drum.

EFFECT: ensuring reliable change-over switching of the drive for the development roller.
