摘要： Movement and/or urging of a developer carrying memer is carried out with high precision.A cartridge that is mountable to an apparatus main assembly of an image forming apparatus, the cartridge includes a developing roller; a frame supporting the developing roller; a movable part movably supported by the frame and movable to a first position and to a second position relative to the frame; and an elastic part provided between the frame and the movable part to urge the movable part. The movable part includes a first force receiving part that receives force from the apparatus main assembly, in a direction of moving from the first position to the second position, and a second force receiving part that receives force from the apparatus main assembly, in a direction of moving from the second position to the first position. When the movable part receives force from the apparatus main assembly at the first force receiving part and is at the second position, the movable part receives urging force from the elastic part in a direction of moving the movable part from the second position to the first position.

摘要： On a projection plane orthogonal to an axial line of a developing agent bearing member, forming an imaginary region surrounded by a plurality of straight lines and edges of electric contacts, while satisfying first, second, and third conditions, disposes the entirety of a positioning region inside an imaginary region. The first condition is that each of the ends of the plurality of straight lines is situated at an edge of the electric contacts or at the center of the developing agent bearing member. The second condition is that the center of the developing agent bearing member is situated at an intersection of the plurality of straight lines, or upon one of the straight lines. The third condition is that each of the straight lines is stipulated so that the area of the imaginary region is maximal, within the constrictions of the first and second conditions.

摘要： A cartridge includes a developing roller rotatable about a rotational axis thereof. A frame is configured to support the developing roller. A lever is connected to the frame, with the lever being movable relative to the frame, and a part of the lever protruding beyond the frame. A surface of the developing roller extends a longer distance in a direction of the rotational axis than a distance that the lever extends in the direction of the rotational axis.
