Abstract: An image forming unit to be attached to an apparatus body of an image forming apparatus includes a first cartridge including a driven portion configured to rotate on a first rotational axis; and a second cartridge configured separable from the first cartridge. The second cartridge includes an input portion configured to receive driving force from the apparatus body; and a drive transmission portion configured to rotate on a second rotational axis and to transmit the driving force to the driven portion.

Abstract: A cartridge includes a photosensitive drum and a discharge opening for permitting discharge of toner removed from the photosensitive drum to outside of the cartridge. The cartridge also includes a coupling member provided adjacent to the discharge opening and configured to output a rotational force, with the coupling member being movable relative to the photosensitive drum between (i) a first position and (ii) a second position retracted from the first position.

Abstract: A rotational force is transmitted to a main assembly side feeding member for feeding the toner into a main assembly side toner accommodating portion from a coupling member provided on a cartridge. The cartridge includes a photosensitive drum, a discharge opening configured to discharge the toner removed from the photosensitive drum toward the main assembly side feeding member, and a coupling member configured to transmit the rotational force to the main assembly side feeding member. The coupling member is movable between a first position for transmitting the rotational force to the main assembly side feeding member and a second position retracted from the first position.

Abstract: A cartridge comprises a frame including a chamber, a photosensitive drum supported by the frame, a first coupling member operatively connected to the photosensitive drum such that a rotational force can be transmitted from the first coupling member to the photosensitive drum, and a second coupling member provided adjacent to an opening in the cartridge. The chamber is in fluid communication with the opening, with the second coupling member forming at least a part of the passageway through which toner can move from the chamber to the opening.

Abstract: 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.
