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.

A recording material processing apparatus includes a guide shaft of which an axial direction extends in a recording material width direction intersecting a discharge direction of a recording material, and an alignment unit that moves along the guide shaft, in which the alignment unit includes a bearing portion that is movably fitted onto the guide shaft, an alignment portion that is provided to be exposed at an outer side in the discharge direction and comes into contact with an end surface of the recording material that is parallel to the discharge direction from an outer side of the recording material to align a position of the end surface, an arm portion that connects the bearing portion and the alignment portion to each other, and a protruding portion that protrudes from a surface of the arm portion to a position outside the recording material in the axial direction of the guide shaft and comes into contact with a surface of a device main body, which is parallel to the discharge direction, in a case where an external force is applied to the alignment unit with the alignment unit being at a position close to the surface.

A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.

A sheet post-processing device comprises: a processing tray; a discharge tray; and a discharge rollers pair. The discharge rollers pair is constituted by a discharge roller which contacts the uppermost surface of sheets stacked in the processing tray and a discharge roller which contacts the lowermost surface of the sheets stacked in the processing tray). The sheet post-processing device discharges a sheet from the processing tray to the discharge tray by rotating the discharge rollers pair in the forward direction, and causes the sheet to be drawn into the processing tray by rotating the discharge roller in the reverse direction in a state in which the rotation of the discharge roller is stopped.

An image forming apparatus, comprising: a housing having a sheet discharge tray, a first opening, and a second opening disposed on an upper side of the first opening; an image forming unit; a sheet discharge path communicating with the first opening; a re-conveying path communicating with the second opening; and a swinging member having a first surface facing the first opening and a second surface, wherein the swinging member has a first end area swingably supported by the housing, a second end area, and a rib; the swinging member is disposed to be movable between a first position and a second position at which the second end area gets higher; and the rib is formed on the second surface opposing the first surface facing the sheet discharge tray in a state where the swinging member is disposed at the second position.

A sheet processing device is for binding sheets together. The sheet processing device includes binding units differing from each other in maximum sheet count, the maximum sheet count being a maximum number of sheets that can be bound at a time; a sheet tray configured to hold sheets until all to-be-bound sheets are placed therein, the number of the to-be-bound sheets being a largest one of the maximum sheet counts of the binding units or smaller; and a stacked-sheet-count limiting unit situated in a thickness direction of the sheets held in the sheet tray. The stacked-sheet-count limiting unit is configured to limit the number of sheets held in the sheet tray by varying a distance from a sheet support surface of the sheet tray on which the sheets are placed, depending on one of the binding units by which the sheets held in the sheet tray are to be bound.

An image forming apparatus has an apparatus main body, a sheet conveyance passage, a cover member, a conveyance unit, a sheet tray, a first sheet feeding portion, and a feed unit. The sheet conveyance passage is inside the apparatus main body. The conveyance unit is inside the cover member and is supported to be pivotable between an open position and a closed position. The first sheet feeding portion has a feed unit. The conveyance unit has a swing guide of which a lower end part is swingably supported on the apparatus main body and which, in the closed position, is located in a first position to face the feed unit and constitute part of the sheet conveyance passage and, in the open position, is located in a second position to be located away from the feed unit.

A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.
