An image forming apparatus includes a stacking unit, an access detecting unit, a malfunction detecting unit, a counting unit, and a process deciding unit. The stacking unit receives, as stacked, a recording material. The access detecting unit detects an access to the stacking unit by an operator. The malfunction detecting unit detects that a conveyance malfunction of the recording material has occurred on a conveying path guiding the recording material supplied from the stacking unit. The counting unit counts, after the access detecting unit detects an access to the stacking unit by the operator in a state that the malfunction detecting unit does not detect that the conveyance malfunction has occurred, the number of the conveyance malfunction detected by the malfunction detecting unit. The process deciding unit decides a process to address the conveyance malfunction based on the number of the conveyance malfunction counted by the counting unit.

A control device includes a processor configured to perform, in a feeding device including a feeding unit that feeds out a feeding target loaded on a loading unit and a cleaning unit that cleans the feeding unit in a state where the feeding target is exhausted from the loading unit, notification control of issuing notification to prompt a user to take out the feeding target from the loading unit on a notification unit in a case where an addition state in which the feeding target is added to the loading unit occurs before the feeding target is fed out and exhausted from the loading unit.

Provided is an image forming apparatus including: an image forming unit configured to form an image on a sheet fed from a container; a trailing edge regulating plate, which is movable in a feeding direction inside the container, and is configured to regulate a trailing edge position of the sheet; a detector configured to automatically detect a sheet size based on the position of the trailing edge regulating plate; and a receiver configured to receive a size of the sheet to be set for the container as a user set size.

An image forming apparatus determines whether crease processing at a plurality of portions set on the sheet includes crease processing on two, front and back surfaces of the sheet; determines, if it is determined that crease processing includes crease processing on the two surfaces of the sheet, whether a connected post-processing apparatus that performs crease processing on a sheet can perform crease processing on the two, front and back surfaces of the sheet by one feeding; and controls, if it is determined that the connected post-processing apparatus cannot perform crease processing on the two surfaces by one feeding, to change, to one of the front and back surfaces of the sheet based on attribute information of the sheet, a surface to be processed in crease processing at the plurality of portions.

An image forming apparatus, including: a printing unit configured to print on a sheet; a bookbinding unit configured to perform a cutting process of cutting a binding member for binding a plurality of sheets before sheets printed by the printing unit are stacked on a stack tray and perform a binding process of binding the sheets by the cut binding member; and a controller configured to cause the bookbinding unit to perform the cutting process of the binding member based on sheet size information, the controller controls, in a case of producing a plurality of copies of bookbound products, not to perform the cutting process of the binding member of a second copy while sheets are stacking as a first copy, but to perform the cutting process of the binding member of a next copy while sheets are stacking as each of the second copy and subsequent copies.

An image processing system includes an image forming unit, an image decoloring unit, a first sheet stacking unit, a second sheet stacking unit, a first detector for the first sheet stacking unit, a second detector for the second sheet stacking unit, and a control unit. The control unit controls a transport path of a sheet discharged from one of the image forming unit and the image decoloring unit.

A device and method for the processing of printed products with one or more transport systems for transporting the printed products between processing stations comprises a transport path lighting system that is divided into segments, wherein the type of illumination of such a segment is with respect to its color, intensity and/or variation in time defined by certain properties of the product located in this section or its production history.

An image forming apparatus includes a housing, a sheet feeding cassette, and a pickup roller positioned above and on a sheet feeding side of the sheet feeding cassette and rotatable to pick up a sheet that is in contact therewith from the sheet feeding cassette. The sheet feeding cassette includes a sheet tray on which a sheet bundle and a packaging member for the sheet bundle are to be accommodated, first and second guides for supporting lateral sides of the sheet bundle and the packaging member, and a first wall on the sheet feeding side of the sheet feeding cassette and a third guide spaced apart from the first wall to support the sheet bundle and the packaging member from a trailing edge side thereof. The height of the first wall is lower than a height of each of the first, second, and third guides.

A sheet conveyance apparatus comprises a first sheet accommodation unit, a second sheet accommodation unit, a conveyance path and a controller. The first sheet accommodation unit and the second sheet accommodation unit are both provided with a movable guide plate which determines the size of an accommodated sheet. The conveyance path conveys a sheet between the first sheet accommodation unit and the second sheet accommodation unit. The controller carries out a control processing so as to change, in a case in which the accommodation size of the first sheet accommodation unit is changed, the accommodation size of the second sheet accommodation unit to be the same as that of the first sheet accommodation unit.
