Patent ID: 8437661

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, wherein said main assembly of the apparatus includes a main assembly side positioning portion, an urging member configured to take an urging position for urging said process cartridge to the main assembly side positioning portion and a retracted position retracted from the urging position, wherein said urging member is provided with an urging portion and a portion-to-be-displaced, said process cartridge comprising: an electrophotographic photosensitive drum; a frame supporting said electro photographic photosensitive drum; a portion-to-be-positioned provided on said frame; a displacing portion provided to move the urging member from to the retracted position by contacting the portion-to-be-displaced when said process cartridge advances along an axial direction of said electrophotographic photosensitive drum in the main assembly of the apparatus, said displacing portion being effective to move the urging member to the retracted position by contacting the portion-to-be-displaced when said process cartridge advances in the main assembly of the apparatus; and a portion-to-be-urged to be urged by the urging member in a state in which said process cartridge is set in the main assembly of the apparatus, wherein, when said process cartridge advances in the main assembly of the apparatus, said portion-to-be-urged is urged toward the main assembly side positioning portion so that said portion-to-be-positioned is abutted to the main assembly side positioning portion by the urging member moving to the urging position after being retracted to the retracted position by said displacing portion, and wherein said portion-to-be-positioned is positioned to the main assembly side positioning portion by said portion-to-be-urged being urged by the urging member in a state in which said process cartridge is set in the main assembly of the apparatus.
