Abstract: A stacking device which is detachably attached to an apparatus body of an image forming apparatus having an abutting member that abuts on a recording material and on which a recording material is stacked includes: a first supporting unit that supports the recording material from a lower side of the recording material; and a second supporting unit that supports an end of the recording material in an attachment/detachment direction of the stacking device. The second supporting unit includes a corresponding region, and a position of the corresponding region agrees with a position of the abutting member abut with the recording material in a width direction which is orthogonal to the attachment/detachment direction. At least a height of the corresponding region in a direction orthogonal to the attachment/detachment direction and the width direction is lower than a height of the abutting member.

Abstract: An image forming apparatus includes an apparatus main body including an opening, an image forming unit, a storage portion, a moving unit, and a control unit. The control unit switches between a first state and a second state, the first state being a state where the moving unit is prohibited from moving and exposing a first sheet when information about a second user different from a first user who has instructed to print a first sheet is received, and the second state being a state where the moving unit is permitted to move and expose the first sheet if information about the second user is received.

Abstract: A sheet storing apparatus includes a plurality of sheet storing units. Each of the sheet storing unit includes a fixed stacking portion configured to stack thereon a sheet conveyed by conveyance roller pairs, and a pushing unit configured to contact an edge of the sheet stacked on the stacking portion and to move the sheet in a direction substantially perpendicular to the sheet conveyance direction. A drive transmission unit for transmitting a driving force generated by a motor to drive the pushing unit is located upstream of the fixed stacking portion with respect to a direction in which the pushing unit moves the sheet. When the pushing unit is moving the sheet, a part of the drive transmission unit enters the inside of a sheet stacking range of the fixed stacking portion.

Abstract: A sheet conveyance apparatus includes a controller controlling a driver to cause a guide to start rotation in a state in which a trailing end in a sheet conveyance direction of a preceding sheet conveyed by a roller pair having a first roller and a second roller such that the trailing end of the preceding sheet is moved from the position above a first guide to a position between a second guide and a sheet support by the rotation of the guide and that a succeeding sheet conveyed by the roller pair subsequently to the preceding sheet passes the position above the first guide after the rotation of the guide. The first roller is rotated by a driving force supplied from a driving source, and the guide rotates about a rotation axis of the first roller while rotating relatively to the first roller.

Abstract: A sheet processing apparatus includes a buffering portion having a reverse conveyance roller pair and an intermediate roller pair, with the reverse conveyance roller pair reversing a conveyance direction of a sheet received from a first conveyance path and delivering the reversed sheet into a second conveyance path and being configured to come into contact with and be separated from each other. The intermediate roller pair is disposed in the second conveyance path and disposed upstream of a conveyance roller pair in a sheet conveyance direction, and the reverse conveyance roller pair is caused to nip a first sheet and a second sheet by causing the reverse conveyance roller pair to abut each other after receiving the second sheet by the reverse conveyance roller pair from the first conveyance path in a state in which the intermediate roller pair nips the first sheet reversed by the reverse conveyance roller pair and the reverse conveyance roller pair is separated from each other.
