摘要： A cartridge includes a photosensitive drum, the movable member movable relative to the photosensitive drum to control an inclination angle of a drive transmission member. The movable member is movable between a first position for reducing an inclination angle of the drive transmission member relative to the photosensitive drum and a second position retracted from the first position. By this, driving connection can be smoothly carried out.

摘要： A method of manufacturing a frame unit from a first unit (60). The first unit includes a first image carrying member (62), a supporting member (73) supporting the first image carrying member, and a frame (71) to which the supporting member is adhered. The first image carrying member includes a first edge portion member (63), and the first edge portion member includes a first restricted portion (63a). The supporting member includes a bearing (73a) engaging with the first edge portion member. The frame includes a first restricting portion (71m) restricting movement of the first image carrying member. The method includes a separating step in which the first image carrying member is separated from the supporting member while in a state in which the supporting member is adhered to the frame.

摘要： A driving-force transmission member (81) includes a coupling portion (81b) that transmits a driving force to a cartridge coupling (63b), a first helical gear portion (81a) that engages with a driven gear (30a) of a cartridge (B) to transmit the driving force, and a second helical gear portion (81e) that engages with a drive gear (105) to receive the driving force. The portions (81b, 81a, 81e) rotate integrally when the driving-force transmission member rotates about the axis of rotation. The driving-force transmission surface is shaped with a twist in the same direction as the driving-force transmission member. Helical teeth of the first helical gear portion are shaped with a twist in the same direction as the driving-force transmission surface. Helical teeth of the second helical gear portion are shaped with a twist in a direction opposite to the twist direction of the helical teeth of the first helical gear portion.
