A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising: an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum; a drum frame supporting the electrophotographic photosensitive drum; and a developing frame supporting the developing roller and movable relative to the drum frame between a contacting position in which the developing roller is in contact with the electrophotographic photosensitive drum and a spacing position in which the developing roller is spaced from the electrophotographic photosensitive drum; characterized by a force receiving device including a first force receiving portion (71; 471; 571) for receiving a first external force and a second force receiving portion (70; 470; 570) for receiving a second external force, wherein the second force receiving portion (70; 470; 570) is movable relative to the developing frame between (i) an operating position in which the second force receiving portion (70; 470; 570) is capable of receiving the second external force to move the developing frame from the contacting position to the spacing position and (ii) a stand-by position in which the second force receiving portion (70; 470; 570) is retracted from the operating position toward an inside of the developing frame, and wherein the first force receiving portion (71; 471; 571) is capable of receiving the first external force to move the second force receiving portion (70; 470; 570) from the stand-by position to the operating position, and wherein the force receiving device is configured to make a distance through which the second force receiving portion (70; 470; 570) moves from the stand-by position to the operating position is greater than a distance through which the first force receiving portion (71; 471; 571) is moved by the first external force. an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum; a drum frame supporting the electrophotographic photosensitive drum; and a developing frame supporting the developing roller and movable relative to the drum frame between a contacting position in which the developing roller is in contact with the electrophotographic photosensitive drum and a spacing position in which the developing roller is spaced from the electrophotographic photosensitive drum; a force receiving device including a first force receiving portion (71; 471; 571) for receiving a first external force and a second force receiving portion (70; 470; 570) for receiving a second external force, wherein the second force receiving portion (70; 470; 570) is movable relative to the developing frame between (i) an operating position in which the second force receiving portion (70; 470; 570) is capable of receiving the second external force to move the developing frame from the contacting position to the spacing position and (ii) a stand-by position in which the second force receiving portion (70; 470; 570) is retracted from the operating position toward an inside of the developing frame, and wherein the first force receiving portion (71; 471; 571) is capable of receiving the first external force to move the second force receiving portion (70; 470; 570) from the stand-by position to the operating position, and wherein the force receiving device is configured to make a distance through which the second force receiving portion (70; 470; 570) moves from the stand-by position to the operating position is greater than a distance through which the first force receiving portion (71; 471; 571) is moved by the first external force.
