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.
Claims16
A cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the main assembly including a main assembly side feeding member for feeding toner toward a main assembly side toner accommodating portion, the cartridge comprising:
- a casing having a chamber;
- a photosensitive drum rotatably supported by the casing, with a part of the photosensitive drum being positioned in the chamber;
- a discharge opening in fluid communication with the chamber such that toner may be discharged from the chamber, through the discharge opening, to the main assembly side feeding member;
- and
- a coupling member configured to transmit a rotational force to the main assembly side feeding member through engagement therebetween, the coupling member being positioned adjacent to the discharge opening such that the toner can move from the chamber to the coupling member and the discharge opening,
- wherein 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.
