Patent ID: 8170444

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, wherein the main assembly of the apparatus includes a main assembly side positioning portion, an urging member rotatable about a rotation axis to take an urging position for urging said process cartridge to the main assembly positioning portion, a retracted position retracted from the urging position, and a stand-by position which is in a movement path of said process cartridge, and wherein the rotation axis, the urging member and a portion-to-be-displaced are arranged in the order named, said process cartridge comprising: an electrophotographic photosensitive drum; process means actable on said electrophotographic photosensitive drum; a portion to be positioned; a displacing portion provided to move the urging member from the stand-by position to the retracted position by contacting the portion-to-be-displaced disposed at a position more remote from the rotation axis than the urging member when said process cartridge advances along an axial direction of said electrophotographic photosensitive drum in the main assembly, said displacing portion being effective to move the urging member to the retracted position by contacting the urging member when said process cartridge advances in the main assembly; a portion-to-be-urged to be urged by the urging member in a state in which process cartridge is set in the main assembly, wherein when said process cartridge advances in the main assembly, 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, 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 process cartridge is set in the main assembly.
