Abstract
A cartridge includes a photosensitive member, a developing member for depositing toner onto the photosensitive member, and a coupling member capable of receiving a driving force for rotating the developing member. The cartridge also includes a movable portion movable between a driving force transmitting position for permitting transmission of the driving force from the coupling member to the developing member and a driving force interrupting position for interrupting the transmission of the driving force from the coupling member to the developing member. A holding portion is provided for holding the movable portion in the driving force interrupting position when the movable portion is in the driving force interrupting position. The movable portion is capable of taking the driving force transmitting position and the driving force interrupting position in a state where the developing member is in a position where the toner is capable of being deposited on the photosensitive member.
