Patent ID: 7860433

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising: an electrophotographic photosensitive drum; a developing roller configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive drum; a drum frame supporting said electrophotographic photosensitive drum; a developing frame supporting said developing roller, said developing frame being movable relative to said drum frame and capable of taking a contacting position in which said developing roller is in contact with said electrophotographic photosensitive drum and a spacing position in which said developing roller is spaced from said electrophotographic photosensitive drum; and a portion-to-be-positioned contactable to the main assembly to position said process cartridge relative to the main assembly when said process cartridge is mounted to the main assembly; a force receiving device including a first force receiving portion configured and positioned to receive a first external force and a second force receiving portion, provided at a higher position than said portion-to-be-positioned, configured to receive a second external force, wherein said second force receiving portion is movable relative to said developing frame, wherein said second force receiving portion is placed in a stand-by position retracted from an operating position provided by said first force receiving portion receiving the first external force below said second force receiving portion, and is movable from the stand-by position to the operating position for moving said developing frame from the contacting position to the spacing position, wherein the operating position is above the stand-by position, and said second force receiving portion is projected beyond a top surface of said process cartridge when said second force receiving portion is in the operating position, and wherein a distance, in a vertical direction, through which said second force receiving portion moves from the stand-by position to the operating position is larger than a distance, in the vertical direction, through which said first force receiving portion is moved by the first external force.
