摘要： A cartridge includes a photosensitive drum and a casing rotatably supporting the photosensitive drum. A coupling is operatively connected to the photosensitive drum so as to be capable of transmitting a driving force toward the photosensitive drum. The coupling includes a main body, a movable portion movable relative to the main body of the coupling between a first position and a second position, and a projection configured to move in a circumferential direction of the coupling relative to the main body of the coupling in response to movement of the movable portion from the first position to the second position.

摘要： A toner container includes a toner accommodating body, a nozzle in fluid communication with the toner accommodating body, and a shutter configured to open and close the opening of the nozzle. A projection is positioned at an end portion of the toner container in a direction of the rotational axis, the projection having an inner peripheral surface facing towards the rotational axis. When the toner container is oriented such that the toner accommodating body is above the nozzle, the nozzle is above the projection, and the projection is at a bottommost side of the toner container, (i) the opening of the nozzle is positioned such that toner may be discharged from a lateral side of the toner container that is above the bottommost side, (ii) the projection includes (ii-i) a first surface facing downward, (ii-ii) a second surface facing downward, and (ii-iii) a third surface facing upward, with the first surface, the second surface, and the third surface being positioned outside the inner peripheral surface of the projection and inside the opening of the nozzle in the direction perpendicular to the rotational axis, (iii) the first surface extends such that a distance in the direction of the rotational axis from the first surface to the toner accommodating body decreases along the first surface in the first rotational direction, (iv) the second surface extends such that a distance in the direction of the rotational axis from the second surface to the toner accommodating body decreases along the second surface in the first rotational direction, (v) a distance, measured along a line that is perpendicular to the rotational axis, from the rotational axis to at least a part of the first surface is less than a distance, measured along a line that is perpendicular to the rotational axis, from the rotational axis to a part of the second surface that is closest from the rotational axis, and (vi) at least a part of the third surface is above an uppermost part of the second surface.

摘要： A packing member for packing a cartridge which is detachably mountable to an image forming apparatus includes: a frame portion including an opening as an entrance for the cartridge, a first recessed portion for accommodating the cartridge, and a limiting portion, provided in the first recessed portion, for limiting a position of the cartridge with respect to the direction crossing a limiting portion of the cartridge; and a cap portion, provided rotatably connected to the frame portion by a hinge portion, for openably covering the opening. The limiting portion limits the position of the cartridge so that the cartridge is located in a position where a grip portion of the cartridge is remoter from the hinge portion than the center line of the cartridge with respect to the crossing direction and a direction crossing an entering direction in which the cartridge enters the frame portion.

摘要： An image forming system includes a toner container and an image forming apparatus to which the toner container is mountable. The toner container includes a projection that includes an inner peripheral surface centered on a central axis of the toner container. When the toner container is oriented in a predetermined direction, the projection has a downward guide surface facing downward and an upward guide surface facing upward. When the toner container is moved downward in a direction of the central axis toward a mounting portion of the image forming apparatus, (i) the downward guide surface is configured to guide a guided member of the image forming apparatus so that the guided member is rotated in a rotational direction about the central axis, and (ii) the upward guide surface is configured to guide the guided member so that the guided member is moved up after the guided member is rotated in the rotational direction by the downward guide surface.
