摘要： A fixing device includes a film, a roller forming a nip with the film, for conveying a sheet while nipping the sheet, a member for urging one of the film and the roller toward the other, a heater for heating one of the film and the roller, a cam, rotationally driven by a motor, for moving the urging member in a releasing direction or a restoring direction of an urging force by the urging member, a gear that swings, depending on normal or reverse rotation of the motor, and a stopper to stop the swinging of the gear. By this arrangement, the rapid rotation of gears that are free from engagement, which can cause impact noise during a transitional process between a gear engagement state in a nip-released state by the roller and a gear engagement state during a nipping function by the roller, can be suppressed.

摘要： A rotating force transmitting part is provided for an electrophotographic photosensitive drum for a main assembly of the electrophotographic image forming apparatus. The main assembly includes a motor-driven shaft having a rotating force applier. The drum is dismountable from the main assembly in a direction substantial perpendicular with an axial direction of the shaft. The part includes a coupler engageable with the force applier to receive a rotational force for rotating the drum when mounted to the main assembly. The coupler moves between a position for transmitting the rotational force for rotating the drum to the drum and a disengaged position inclined away from the axis of the drum. When the cartridge is dismounted from the main assembly substantially perpendicular to the axis of the drum, the coupler moves from the transmitting position to the disengaging position.

摘要： A process cartridge comprises a photosensitive drum, a developing roller, and a coupling member. The coupling member is capable of inclining relative to the photosensitive drum such that the coupling axis inclines relative to the drum axis. A regulating portion surrounds the coupling member so as to confine the range of inclination of the coupling member. The regulating portion is provided with a recess that recesses in a direction away from the drum axis and away from the developing roller. An angle between the coupling axis and the drum axis is larger when at least a part of the coupling member is in the recess than when the coupling member contacts another portion of the regulating portion.
