PROCESS CARTRIDGE AND IMAGE FORMING DEVICE Russian patent published in 2019 - IPC G03G16/00 

FIELD: image forming devices.

SUBSTANCE: present invention relates to a process cartridge, in which there is an electrophotographic photosensitive drum and a developing roller, made with possibility of connection to each other and departure from each other. Disclosed group of inventions includes a process cartridge and an electrophotographic image forming device for forming an image on a recording material. Process cartridge comprises: photosensitive drum, developing roller, drum frame for supporting said photosensitive drum, developing frame for supporting said developing roller, wherein said developing frame is supported by said drum frame with possibility of rotation about axis of rotation, wherein said developing frame is movable relative to said drum frame between a contact position in which said developing roller is in contact with said photosensitive drum and a spaced position in which said developing roller is spaced from said photosensitive drum, the force receiving element, having an end and an ejectable portion, wherein said force receiving element is configured to move between an adjustment position and an op working erating position, wherein said end is closer to rotational axis when said force receiving element is in adjustment position than when said force receiving element is in working position, pushing member including first portion in contact with and pushing said dispensed portion, second portion and elastic section located between said first section and said second section, wherein when force is applied to said end of said force receiving element, when said force receiving element is in working position, said developing frame is movable such that said developing roller is in spaced position and said resilient portion is configured to be resilient deformation, when said force-receiving element is in adjustment position.

EFFECT: creation of a reduced process cartridge, in which the electrophotographic photosensitive drum and the developing roller are made with possibility of contact and removal from each other, and a reduced image forming device, into which such a process cartridge can be installed with possibility of removal, as well as creation of process cartridge, in which electrophotographic photosensitive drum and developing roller are made with possibility of contact with each other and departure from each other, in which during handling of process cartridge or during transportation of process cartridge, force-receiving section is not damaged.
