Abstract: An optical scanning device includes two cleaning holders. The two cleaning holders each include two cleaning members. The two cleaning holders are connected to a wire-shaped member. In accompaniment of circulation of the wire-shaped member, the two cleaning holders travel to cause the cleaning members to slide on corresponding transmissive members. Upon one of the two cleaning holders coming into contact with a first stopper at one end of its travel path, a circulating direction of the wire-shaped member is reversed. Upon the other of the two cleaning holders coming into contact with a second stopper at one end of its travel path, the wire-shaped member stops circulating.

Abstract: A light scanning device includes a housing, a plurality of permeable members, a plurality of cleaning members, a plurality of cleaning holders, a linear member, and a driving unit. The plurality of permeable members close the respective plurality of the emission ports. The plurality of cleaning holders extend over the plurality of the permeable members adjacent to one another. The plurality of the cleaning holders each have a holding unit that holds at least the two cleaning members. The linear member is connected to the plurality of the cleaning holders. The driving unit causes the linear member to run circularly. The cleaning members each slide on the corresponding permeable member in association with the linear member running circularly. The cleaning holders each connected to the linear member at a center of the holding unit in an extending direction of the holding unit.

Abstract: The present invention includes a supporting member that supports a first roller and a second roller, a first actuator that rotates the supporting member, a first gear that is connected to an end of second roller on the first actuator side, a second gear that is threadably engaged with the first gear, a third gear that rotates coaxially with the second gear, an input gear that threadably engages with the third gear, and a second actuator that transmits a rotational force to the input gear. The third rotation shaft extends in parallel in a first plane that includes the leading edge and the trailing edge of the nip, the first actuator rotates the supporting member between a first position at which the sheet is received from the leading edge of the nip and a second position at which the sheet is received from the trailing edge of the nip.

Abstract: A copier includes a developing unit, a toner container, a first movable unit, and a second movable unit. The first movable unit carries the developing unit and is movable between a close position where a developing roller of the developing unit is located close to a photosensitive drum and a distant position where the developing roller is located away from the photosensitive drum. The second movable unit carries the toner container and is configured to drag the first movable unit from the close position to the distant position. The copier is configured so that while the second movable unit is located at a standby position for the drag, a clearance is formed between the first and second movable units to avoid physical contact between the first and second movable units.

Abstract: A sheet-conveying device designed to feed a sheet fed thereto through a fixing device toward a discharge unit includes first and second conveyance guides facing each other so as to define a sheet conveyance path and each having a conveying member designed to feed the sheet. The first conveyance guide includes a blower opening facing the sheet conveyance path for blowing air onto the sheet conveyance path, an exhaust opening provided on a downstream side in a sheet feeding direction with respect to the blower opening for removing air that has been blown onto the sheet conveyance path and discharging it outside the device.
