An image forming apparatus includes an apparatus main body, an output tray, and a holding member. The output tray is rotatable about a first rotation shaft between a closed position and an open position. The holding member is rotatable about a second rotation shaft. The output tray comes into contact with the holding member halfway through rotation of the output tray from the closed to the open position. When the output tray is rotated to the open position, the holding member rotates to a retracted position while being in contact with the output tray. When viewed in a direction crossing a recording-material discharge direction, the first rotation shaft is located downstream from the second rotation shaft in the discharge direction, and a center of gravity of the holding member is located downstream from the second rotation shaft in the discharge direction when the holding member is at the retracted position.

An apparatus includes an openable and closable cover, a movable member disposed in the apparatus main body and to be exposed outside when the cover is opened, an openable and closable support member that supports the movable member, and a support shaft that supports the cover and the support member. The movable member and the support member are moved together with the cover as the cover rotates about the support shaft. The support shaft can move between a first position at which the support shaft supports the cover and the support member and a second position at which the support shaft does not support the cover and supports the support member. Moving the support shaft to the second position allows the cover to be detached from the apparatus main body.

An image forming system includes: an image forming apparatus that forms a first image according to a job on a plurality of first sheets and inserts a second sheet between the plurality of first sheets; a cutting processor that sequentially performs cutting processing on the plurality of first sheets and the second sheet that are conveyed from the image forming apparatus; and a sheet discharging tray on which an output object obtained by the cutting processing on each of the plurality of first sheets and a slip sheet obtained by the cutting processing on the second sheet are stacked, wherein the cutting processor performs the cutting processing on each of the plurality of first sheets in accordance with a first cutting condition, and performs the cutting processing on the second sheet in accordance with a second cutting condition different from the first cutting condition.

A sheet discharge apparatus includes a stack portion, a reversing unit configured to reverse a reversing sheet, a support member configured to support a lower surface of the reversing sheet, a discharging unit configured to discharge a discharging sheet from the apparatus body, a pivotable member arranged above the stack portion, and a detector configured to output a detection signal that changes according to a pivot angle of the pivotable member. When viewed in a sheet width direction perpendicular to the first conveyance direction, a pivoting locus in which the pivotable member pivots overlaps the support member.

A sheet discharging apparatus includes a sheet supporting portion supporting a sheet discharged out of a nip portion nipping the sheet and a guide portion provided opposed to an upper surface of the sheet fed out of the nip portion. The guide portion includes a fixed restricting portion restricting a rear end of the sheet with respect to a sheet discharging direction to moving upward away from an extension line in a sheet discharging direction of the nip portion after passing through the nip portion.

A sheet discharge device includes: at least one processor; a conveyance unit configured to convey a sheet along a conveyance path; a discharge unit to which the sheet is discharged; a storage unit that is provided in a middle of the conveyance path and temporarily stores the sheet; an alignment unit provided in the discharge unit and configured to align the sheet in a width direction intersecting a convey direction of the sheet, in which the processor is configured to change a method of aligning the sheets by the alignment unit between a case where storage control for storing the sheets in the storage unit is performed and a case where the storage control is not performed.

A driving device includes: a frame disposed in the driving device to support a driven unit driven by the driving device, the frame including a first portion, a distance from which to an outer wall of an accommodation device that accommodates the driving device is shorter, and a second portion, a distance from which to the outer wall is longer than the distance from the first portion to the outer wall; and a driving unit disposed between the second portion and the outer wall, at least a part of the driving unit being away from the outer wall by the distance between the first portion and the outer wall or more.

An image forming apparatus includes a placing portion onto which a recording medium having an image formed is to be placed, and an opening-closing member that covers an opening provided at least at one side face of the placing portion and automatically opens the opening with a predetermined timing.

An image forming apparatus includes a photosensitive drum, a development device, a fixing device, an apparatus main body, and a fan including a rotating shaft that extends in a longitudinal direction of the photosensitive drum and a blade around the rotating shaft. The development device develops a toner image on the photosensitive drum. The fixing device fixes the toner image from the photosensitive drum to a recording material. The apparatus main body is provided with a discharge port from which the toner-fixed recording material is discharged. A length of the fan rotating shaft in the longitudinal direction is longer than a diameter of a rotational trajectory of the blade. The fan is provided on a downstream side of the fixing device in a discharge direction in which the recording material is discharged from the discharge port and overlaps a part of the development device when viewed in a vertical direction.

A sheet discharge device includes a sheet discharge portion, a sheet loading portion, and a stopper mechanism. The stopper mechanism includes a first stopper supported pivotably to a first retraction position and a first restriction position, a second stopper that is movable to a first position at which the second stopper is housed along a downstream end part of the sheet loading portion and a second position apart from the first position to a downstream side in a sheet discharge direction and is supported pivotably to a second retraction position and a second restriction position, and a link mechanism connecting the first stopper to the second stopper. When the second stopper is disposed at the first position, the first stopper is disposed at the first restriction position, and when the second stopper is disposed at the second position, the first stopper is disposed at the first retraction position.
