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.

摘要： A toner container includes a toner accommodating body and a nozzle including an opening configured to form a part of a discharge passageway through which toner may be discharged to outside of the toner container. A shutter is configured to open and close the opening of the nozzle, with the shutter being rotatable about a rotational axis between a first position in which the shutter closes the opening of the nozzle and a second position in which an opening of the shutter aligns with the opening of the nozzle to form the discharge passageway. A projection is positioned at an end portion of the toner container, with the projection including a first surface, a second surface, and a third surface. 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 first surface faces downward, (iii) the second surface faces downward, and (iv) the third surface faces upward.

摘要： A cartridge includes a coupling member, a transmitted member, and a rotary member. The transmitted member includes an accommodating portion configured to accommodate the coupling member, and a protruded portion integrally formed with an inner wall of the accommodating portion and protruding from the inner wall toward an inside of the accommodating portion. The coupling member includes a free end portion having a rotational force receiving portion that receives a rotational force, a connected portion connected to the transmitted member in such a manner that at least a part of the connected portion can be accommodated in the accommodating portion, and a recessed portion provided at the connected portion so that the protruded portion can enter. An inclination angle of a rotation axis of the coupling member relative to a rotation axis of the transmitted member is variable.

摘要： A unit for use with an image forming apparatus includes: a frame; a developer accommodating portion; a sheet member, contact to a rotatable member and provided on the frame along a longitudinal direction of the rotatable member; a first end portion seal member for preventing, at a longitudinal end portion, the developer from leaking out from between the frame and the rotatable member; and a second end portion seal member for preventing the developer from leaking out from among the first end portion seal member, the sheet member and the frame. The second end portion seal member is formed by injecting, on the frame, a resin material having an elastic modulus smaller than an elastic modulus of the frame so as to contact with the first end portion seal member and the sheet member.

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.
