An image forming apparatus forming an image on a sheet, including: an exterior member movable with respect to an apparatus main body; a locking portion locking the exterior member to the apparatus main body such that the exterior member is not moved with respect to the apparatus main body; a display portion which is disposed on the exterior member and displays a state of the locking portion; and a light source turning on the display portion, in which the display portion includes a thin portion which is a part of the exterior member, has a thickness less than thicknesses of other portions of the exterior member, and transmits light from the light source.

A recording system includes a printer, a post-processing apparatus, and a first support to be mounted on a floor outside a mounting area of the printer. The printer includes a manual feed tray and an opening/closing portion each configured to be moved outward from a body of the printer to enable a process. The post-processing apparatus is located, in a Z direction, above the manual feed tray and the opening/closing portion that were moved. The first support supports the post-processing apparatus and forms a space in which the manual feed tray and the opening/closing portion are moved.

A sheet processing apparatus is configured to sandwich one or more sheet media in a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet. The sheet processing apparatus includes circuitry configured to control insertion processing to insert the one or more sheet media into the two-ply sheet based on a length of the two-ply sheet in a conveyance direction, a length of one of the one or more sheet media in the conveyance direction, and a number of the one or more sheet media.

An image forming apparatus includes a drive roller configured to be rotated by a drive source, a first rotation member configured to be driven to rotate by the drive roller, and a second rotation member configured to be driven to rotate by the drive roller. The drive roller, the first rotation member, and the second rotation member are configured to convey a sheet in a state where the sheet is present at a first nip portion and a second nip portion at the same time.

An accommodating device includes a device body, an accommodating unit that accommodates a medium in the device body, and an expanding and contracting member that expands and contracts to connect the accommodating unit to the device body so as to be pulled out and has a part fixed to the accommodating unit on an inner side with respect to a side surface of the accommodating unit in an intersecting direction with a pulling direction of the accommodating unit and on a lower side of the accommodating unit in a vertical direction.

A conveyance device includes a tray on an upper surface of the conveyance device and an upper guide below the tray. The tray receives a sheet, and the upper guide defines a conveyance path in which the sheet is conveyed. The upper guide is movable together with the tray to open the conveyance path.

A fixing device includes first and second rotatable members, a moving mechanism, a flag, a sensor, a movable guide, and a stationary guide. The moving mechanism is configured to move the first rotatable member away from the second rotatable member. The flag is provided downstream of the nip with respect to a recording material feeding direction and retractable by passing of the recording material. The sensor is configured to detect whether or not the flag is retracted by contact with the recording material. The movable guide is movable together with the first rotatable member away from the second rotatable member and from the flag by the moving mechanism. The stationary guide is fixed at a position opposing the flag, irrespective of a position of the movable guide member. The stationary guide does not move together with the movable guide.

According to one embodiment, an image processing apparatus includes an apparatus main body, a first rotating body, a second rotating body, and a connection member. The first rotating body is configured to be openable and closeable and provided in the apparatus main body. The second rotating body is provided in the first rotating body. The second rotating body is configured to be openable and closable from the first rotating body in the same direction as that of the first rotating body. The connection member is linear. The connection member is configured to connect the apparatus main body and the second rotating body to each other and to restrict a rotation angle of the second rotating body.

A rotating device includes: an opening-closing portion supported so as to be openable and closable with respect to a support body; a drive unit provided on the support body; a first rotating body provided on the support body and rotated by a drive force of the drive unit; a driven portion provided in the opening-closing portion; a second rotating body provided in the opening-closing portion, rotated by a transmitted rotational force, and transmitting the rotational force to the driven portion; and an annular body formed in an annular shape, wound around the first rotating body and the second rotating body, maintaining the winding state in both an open state and a closed state of the opening-closing portion, and transmitting the rotational force of the first rotating body to the second rotating body.

An image forming apparatus configured to form an image on a sheet includes a main body, an opening and closing part, a link part, and an urging member. The link part is connected to the main body and the opening and closing part. When the opening and closing part moves between open and closed positions, the link part moves perpendicular to a direction along a rotating shaft of the link part to contact and be received by the main body. The opening and closing part can move in a state in which the link part and the main body contact each other. When the opening and closing part is in the closed position, the link part and the main body are separated from each other, and the opening and closing part is urged toward the main body by the link part urged by the urging member.
