Abstract: An image forming apparatus includes an image forming unit and developing containers. The image forming unit includes developing stations to form an image on a print medium with toners, based on input image data. The developing containers contain the toners and are attachable to and detachable from the developing stations. The developing containers include a first developing container containing a first toner and a second developing container containing a second toner having a higher luminescence intensity under invisible light than the first toner. The first toner and the second toner are toners that form an image having a higher luminescence intensity under the invisible light than under visible light. The image forming unit adheres the second toner to the print medium before adhering the first toner when the image forming unit superimposes the first toner and the second toner one atop another on the print medium.

Abstract: 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.

Abstract: A developing device includes a developer container including first and second chambers, first and second communication portions to permit the developer to communicate with the first and second chambers, first and second screws provided in the first and second chambers, respectively, and a developer discharging portion. The developer discharging portion is provided in a passage continuous with the first chamber and downstream of the first communication portion. In the developing device, a discharging method includes a step for inserting a shielding member into the second communication portion via an inserting opening of the developer container, and a step for discharging the developer from the developing device via the developer discharging portion, by rotating the first and second screws in a same direction as a direction of rotating during a developing operation in a state where the shielding member is inserted into the second communication portion.

Abstract: A developing cartridge includes a housing, a developing roller, a shaft, a first cam, and an elastic member. The housing has a first outer surface at one end portion of the housing in a first direction. The developing roller is rotatable about a first axis extending in the first direction. The shaft is along a second axis extending in the first direction. The shaft is movable in the first direction relative to both the housing and the developing roller. The first cam is at one end portion of the shaft in the first direction. The first cam is movable in the first direction together with the shaft. The elastic member is positioned outward of the shaft in a radial direction of the shaft. The elastic member is positioned between the first outer surface and the first cam in the first direction.

Abstract: An assembly for an image forming device includes an access door movable between an open position permitting replacement of a replaceable unit and a closed position. An electrical connector in the image forming device is movable between a retracted position and an extended position. In the retracted position the electrical connector is disengaged from a corresponding electrical connector of the replaceable unit when the replaceable unit is installed in the image forming device. In the extended position the electrical connector is engaged with the corresponding electrical connector of the replaceable unit. The electrical connector is operatively connected to the access door such that movement of the access door from the closed to the open position moves the electrical connector from the extended to the retracted position and movement of the access door from the open to the closed position moves the electrical connector from the retracted to the extended position.

Abstract: 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.
