Electrophotographic image forming apparatus and process cartridge therefor

摘要

A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the process cartridge includes an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum with a developer;a frame for rotatably supporting the electrophotographic photosensitive drum; a supporting member, rotatably journaled in the frame, for rotatably supporting the developing roller at a position away from a center of rotation thereof; an urging member for elastically urging the frame to urge the developing roller toward the electrophotographic photosensitive drum.
