摘要： A developer container includes a casing having a developer accommodating chamber and a waste-developer accommodating chamber, conveying member, a conveying-member accommodating unit, and a supporting member. The conveying member conveys waste developer in a longitudinal direction of the waste-developer accommodating chamber. The conveying-member accommodating unit accommodates the conveying member therein and has a first opening and a second opening. The first opening is provided in an upstream end portion and allows the waste developer to move from outside of the conveying-member accommodating unit to the inside of the conveying-member accommodating unit. The second opening allows the waste-developer to move from the inside of the conveying-member accommodating unit to the waste-developer accommodating chamber. The supporting member is provided on the casing. The supporting member supports the conveying-member accommodating unit such that the conveying-member accommodating unit is movable in directions perpendicular to the longitudinal direction relative to the casing.

摘要： A developing device includes a developer cartridge and a developing unit. The developer cartridge, in some instances, may include a shutter. This shutter may have a wall for closing a developer supply hole, and be movable, with respect to a developer cartridge casing, between an open position where the supply hole is opened by the wall and a closed position where the supply hole is closed by the wall. The shutter may further include a protrusion that is movable with respect to the wall of the shutter between a first position and a second position in an axial direction. The protrusion, in the first position, is engageable with a developing unit and, in the second position, would be disengaged from the developing unit.

摘要： An image-forming device includes a main casing, a belt accommodated in the main casing, developing units arranged along the belt, a drawer configured to detachably support the developing units, the drawer configured to move to a position inside the main casing and to a position outside the main casing, and the drawer having a leading end and a trailing end in a pulling direction from the inside position to the outside position; and a guide configured to guide the drawer and to move between a first position and a second position when the drawer is at the inside position, the second position being farther from the belt than the first position from the belt. When the guide is at the second position, the guide is configured to be tilted downward relative to a horizontal direction such that the leading end is lower than the trailing end.

摘要： An image forming apparatus includes a main frame, a plurality of process cartridges, a cartridge-supporting body, a belt, a waste toner cartridge, a contact-separation mechanism, and a collective conveying unit. Each process cartridge includes a photosensitive drum and a drum cleaning unit collecting waste toner on the drum. The cartridge-supporting body is movable between an internal position inside the frame and an external position outside the frame. The belt confronts the process cartridges in the internal position. The waste toner cartridge accommodates the waste toner collected from the drums. The contact-separation mechanism moves the cartridge-supporting body between a contact position where the drums are in contact with the belt and a separated position where the drums are out of contact with the belt. The collective conveying unit aggregates waste toner collected from drums and conveys collectively the aggregated waste toner to the waste toner cartridge.

摘要： An apparatus main body includes a main casing and a cover configured to rotatably move about a rotational axis located below an opening between an open position and a closed position. A drum cartridge includes a photosensitive drum and is configured to be installed into the apparatus main body through the opening. A developing cartridge includes a developing roller and is configured to be installed into the apparatus main body through the opening. A swing plate is attached swingably to the apparatus main body. The swing plate supports the developing cartridge. The swing plate includes a guide configured to guide installation of the developing cartridge into the apparatus main body. The swing plate is configured to swingably move in a state where the drum cartridge and the developing cartridge are installed in the apparatus main body, thereby causing the developing roller to move relative to the photosensitive drum.

摘要： A toner cartridge includes a toner supply pipe and a first shutter. The toner supply pipe has a toner supply opening. When the toner cartridge is mounted onto a main unit, the toner supply pipe moves through an insertion opening from an outside position at which the toner supply opening is located outside a developing frame to an inside position at which the toner supply opening is located inside the developing frame. The first shutter is provided at the toner supply pipe. The first shutter moves relative to the toner supply pipe between an open position at which the toner supply opening is opened and a closed position at which the toner supply opening is closed. The first shutter moves relative to the toner supply pipe from the closed position to the open position in a state where the toner supply pipe is located at the inside position.
