摘要： An image forming apparatus comprises: (i) a main assembly including a spacing member and a movable member movable while supporting the spacing member, wherein the spacing member is movable relative to the movable member between a normal position and a retracted position retracted from the normal position; and (ii) a process cartridge detachably mountable to the main assembly. The process cartridge includes a spacing force receiving portion configured to receive a spacing force for moving the developing roller in a direction away from a photosensitive drum, from the spacing member of the main assembly, and a contact portion configured to contact the spacing member to retract the spacing member. When the spacing member is in the normal position, the spacing member is capable of applying the spacing force to the spacing force receiving portion by movement of the movable member, and wherein the spacing member is retractable from the normal position to the retracted position by being contacted by the contact portion of the process cartridge.

摘要： A cartridge (B1) is mountable to an apparatus main assembly (A1) of an image forming apparatus, the apparatus main assembly (A1) having mounted a photosensitive drum (10) separate from the cartridge (B1). The cartridge (B1) comprising: a developing roller (13) including an elastic layer (13d) for bearing developer (t), wherein the elastic layer (13d) can be pressured against the photosensitive drum (10); a frame (16, 34, 36, 46) supporting the developing roller (13); a drive input member (180, 280) configured to receive input of a rotational force to rotate the developing roller (13); a movable part (70) movably supported by the frame (16, 34, 36, 46) and movable to a first position and to a second position relative to the frame (16, 34, 36, 46); and an elastic part (71) provided between the frame (16, 34, 36, 46) and the movable part (70) to urge the movable part (70). The movable part (70) includes a first force receiving part (70a) configured to receive a first external force from the apparatus main assembly (A1), in a direction of moving from the first position to the second position, and a second force receiving part (70g, 170g) configured to receive a second external force from the apparatus main assembly (A1), in a direction of moving from the second position to the first position. When the movable part (70) receives the first external force from the apparatus main assembly (A1) at the first force receiving part (70a) and is at the second position, the movable part (70) receives an urging force (F 10) from the elastic part (71) in a direction of moving the movable part (70) from the second position to the first position. The first force receiving part (70a) is configured to receive the first external force from the apparatus main assembly (A1) so that, in a state that the cartridge (B1) is mounted on the apparatus main assembly (A1), the movable part (70) is at the second position and the elastic layer (13d) is pressured against the photosensitive drum (10) via the elastic part (71) and the frame (16, 34, 36, 46). The second force receiving part (70g, 170g) is configured to receive the second external force from the apparatus main assembly (A1) so that, in a state that the cartridge (B1) is mounted on the apparatus main assembly (A1), the movable part (70) is at the first position and the elastic layer (13d) is spaced from the photosensitive drum (10).

摘要： An image forming apparatus comprises (i) a main assembly including a spacing member, and (ii) a process cartridge detachably mountable to the main assembly. The process cartridge includes a spacing force receiving portion configured to receive a spacing force for moving a developing roller away from a photosensitive drum, from the spacing member of the main assembly, and a contact portion configured to contact the spacing member to retract the spacing member. The spacing member is movable between three different positions which are, (a) a first position for applying the spacing force to the spacing force receiving portion to move the developing roller in a direction away from the photosensitive drum, (b) a second position deviated from the first position in a direction away from the spacing force receiving portion to permit the developing roller to approach to the photosensitive drum, and (c) a third position which is a retracted position provided by contacting the contact portion to avoid interference with the process cartridge.
