A sheet separation device is configured to separate a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at one end as a bonding portion of the two-ply sheet. The sheet separation device includes a conveyance roller pair and circuitry. The conveyance roller pair is configured to convey the two-ply sheet while nipping the two-ply sheet, when separating the non-bonding portion of the two-ply sheet. The circuitry is configured to control sheet conveyance. The circuitry is configured to stop the conveyance roller pair, cause a leading end of the two-ply sheet conveyed toward the conveyance roller pair to contact a nip region of the conveyance roller pair while the conveyance roller pair is stopped, and start the conveyance roller pair to rotate to nip the two-ply sheet.

Provided are a film cartridge, a film unit, and a layer transfer device capable of restraining a supported layer including a transfer layer from being touched by an operator and restraining the supported layer remaining on the supporting layer remaining on a supporting layer from coming off. A film cartridge includes a supply reel on which a multilayer film including a supported layer with a transfer layer included therein and a supporting layer is wound, and a take-up reel on which to take up the multilayer film. The multilayer film is wound on a supply shaft in such a manner that the supported layer is in contact with the supply shaft, and the multilayer film is wound on the take-up shaft in such a manner that the supported layer is in contact with the take-up shaft.

A cutting device is configured to cut, in an arc shape, an end of a sheet conveyed in a conveyance direction. The cutting device includes an arc-shaped cutting blade; a switching mechanism; and a contact-and-separation mechanism. The switching mechanism is configured to switch a posture of the cutting blade in accordance with a position of the sheet facing the cutting blade. The contact-and-separation mechanism is configured to bring the cutting blade into contact with the sheet in a contact direction orthogonal to a surface of the sheet and away from the sheet in a separation direction opposite the contact direction, to cut the end of the sheet in the arc shape.

Disclosed is a layer transfer device for transferring a transfer layer onto a toner image formed on a sheet, in which a replacement of a film cartridge is easy for a user. The layer transfer device includes a housing, a film cartridge, and a holder. The film cartridge includes a supply reel including a supply shaft on which a multilayer film including a supported layer including a transfer layer, and a supporting layer supporting the supported layer is wound, and a take-up reel including a take-up shaft on which to take up the multilayer film. The holder supports the film cartridge, and is installable into and removable from the housing while supporting the film cartridge.

An information processing apparatus includes a sheet holder, a conveyor, a wireless writer, a wireless reader, and a controller. The sheet holder accommodates a sheet. The conveyor conveys the sheet from the sheet holder. The wireless writer writes data to a wireless tag on a first sheet. The wireless reader reads data from the wireless tag on the first sheet. The controller ejects a second sheet from the sheet holder when the data written in the first sheet by the writer and the data read from the first sheet by the reader are different from each other.

A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.

An image forming apparatus includes a processing tray, a post-processing controller, and a detection sensor. The processing tray is configured to support a sheet or a sheet bundle on which a post-processing is to be executed. The post-processing controller is configured to execute the post-processing on the sheet positioned on the processing tray. The detection sensor is configured to detect an object in a predetermined detection range including a space above the processing tray. The post-processing controller stops execution of the post-processing when the detection sensor detects the object at a determination timing other than a timing at which passage of the sheet or the sheet bundle through the detection range is estimated.

A sheet processing apparatus includes: a second conveying roller pair that receives and conveys a sheet conveyed by a first conveying roller pair; a first folding roller pair that forms a first fold on the sheet; and a first rotation unit capable of rotating the second conveying roller pair and the first folding roller pair. One roller of the second conveying roller pair and one roller of the first folding roller pair are a common roller shared therebetween. The second conveying roller pair causes the sheet to be deflected and guided to the first folding roller pair, and the first folding roller pair forms the first fold on the deflected sheet by rotating the first rotation unit in a certain direction in a state in which the sheet is held by the first conveying roller pair and the second conveying roller pair.

Provided is a sheet folding apparatus for folding sheets, including: a feeding-roller pair; a loop-forming space provided downstream from the feeding-roller pair, for forming a sheet loop; a pushing member for pushing the looped sheet; a folding-roller pair for nipping a prescribed part of the sheet pushed by the pushing member, thereby to fold the sheet; and a path provided between the feeding-roller pair and the folding-roller pair, for guiding the sheet fed from the feeding-roller pair toward the loop-forming space.

According to one embodiment, an image forming apparatus includes a reading unit, a heating unit, and an updating unit. The reading unit reads area designation information for designating an area to be decolored in areas of a sheet on which an image that can be decolored by heating is formed and history information for indicating the number of times of performing decoloration in the past for each area of the sheet from a wireless tag attached to the sheet. The heating unit heats the area based on the area designation information read by the reading unit. The updating unit updates the history information stored in the wireless tag which corresponds to the area heated by the heating unit.
