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.
