A post-process apparatus may include: a first operation portion that accepts a sheet conveyed from an image forming apparatus and performs a first operation based on a job involved with the sheet, a second operation portion that accepts a sheet manually inserted into the post-process apparatus and performs a second operation different from the first operation, and a control unit that determines timing to perform the second operation in accordance with a condition of the first operation performed.

A layer transfer device includes a housing main body having an opening, a cover movable between an open position in which the opening is open and a closed position in which the opening is closed, a heating member provided in the housing main body and configured to heat a multilayer film and a sheet, a pressure member provided on the cover and configured to nip the multilayer film and a sheet laid on the multilayer film between the heating member and the pressure member, and a shutter movable between a protecting position in which the heating member is covered with the shutter, and a retreated position in which the shutter is away from the protecting position. The shutter is in the protecting position when the cover is in the open position.

A sheet processing apparatus includes a conveyor, a processing tool, a processing-tool contact-and-separation device, a processing-tool moving device, and a processing-tool facing device. The conveyor conveys a sheet. The processing tool processes the sheet. The processing-tool contact-and-separation device brings the processing tool into contact with the sheet and separates the processing tool from the sheet. The processing-tool moving device moves the processing tool in an intersecting direction intersecting a conveyance direction of the sheet. The processing-tool facing device faces the processing tool with the sheet interposed between the processing-tool facing device and the processing tool. The processing-tool contact-and-separation device includes a regulating member configured to regulate movement of the sheet in a different direction from both the conveyance direction and the intersecting direction.

An image forming system includes: a first image forming apparatus including a first fixer that fixes an image formed on a recording medium to the recording medium; a second image forming apparatus including a second fixer that fixes an image formed on the recording medium to the recording medium, the second image forming apparatus being connected to a downstream side of the first image forming apparatus in a transport direction of the recording medium; and a hardware processor that determines first transport control content in which the recording medium is transported in the first image forming apparatus and the second image forming apparatus, and sets second transport control content so that the recording medium that has been processed by the first fixer is processed in a different position by the second fixer.

An image forming apparatus includes a sheet separation device, a first sheet feeder, a second sheet feeder, an image forming device, and circuitry. The 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 a bonding portion of the two-ply sheet. The first sheet feeder is configured to feed the two-ply sheet. The second sheet feeder is configured to feed an inner sheet to be inserted between the two sheets. The image forming device is configured to form an image on a surface of the inner sheet. The circuitry is configured to cause the first sheet feeder to feed the two-ply sheet, perform a sheet separating operation on the two-ply sheet and cause the second sheet feeder to start feeding the inner sheet before completion of the sheet separating operation on the two-ply sheet.

An image forming apparatus includes: an image former that forms an image with toner containing wax on an image forming medium; a first paper loading part that loads the image forming medium and is located downstream of the image former; a laminator that laminates a film on the image forming medium; a second paper loading part that loads the image forming medium and is located downstream of the laminator; a first path that extends from the image former to the first paper loading part; a second path that extends from the image former to the laminator; a switcher that switches a conveyance path of the image forming medium to either the first path or the second path; and a hardware processor that causes the switcher to switch the conveyance path to the second path when the laminator laminates the film on the image forming medium.

A printing system includes an information processing apparatus including first circuitry and an image forming apparatus. The first circuitry is configured to receive designation of superimposing an image of a particular color on a print target image, associate the image of the particular color with the print target image in response to a reception of the designation of superimposing, and transmit print data including the print target image and the image of the particular color to the image forming apparatus. The image forming apparatus includes second circuitry configured to receive the print data and interpret the print data, and a printer engine configured to superimpose the image of the particular color on the print target image in printing, according to interpretation of the print data.

A post-processing apparatus according to an embodiment includes a processing tray, a post-processing section, a sensor, and a control section. A sheet supplied from an image forming apparatus is led into the processing tray through a lead-in path. The post-processing section applies post-processing to the sheet sent from the processing tray. The sensor detects an object passing a detection space in the lead-in path. The control section controls operation of the post-processing section based on a time in which the sensor detects the object.

An external cooling device 101 is connectable to an image forming apparatus 100. The external cooling device 101 improves cooling power of a recording material S after toner image fixation. In this case, even when a heating amount of the fixing device 11 is increased, a temperature of the recording material S stacked on a stacking unit 60 can be lowered to not more than a predetermined temperature at which sticking does not occur. Further, the number of sheets stackable on said stacking unit 60 can be increased. By this, a user is capable of adjusting glossiness without concern for the sticking of the recording materials S on the stacking unit 60. Further, the user is not required to frequently carry out the recording material S of the stacking unit 60. That is, it is possible to provide an image forming system 1X capable of flexibly meeting the recording materials S of various kinds.
