An image processing apparatus performs a binding process for binding a plurality of sheets. When a binding unit configured to bind sheets without using a staple performs the binding process, the image processing apparatus adds a mark for identifying a position where the binding process is performed.

An image forming apparatus includes a moving member that is movable between a first position and a second position different from the first position, first stop member that is disposed corresponding to the first position and comes into contact with the moving member to stop the moving member in the first position, a second stop member that is disposed corresponding to the second position and comes into contact with the moving member to stop the moving member in the second position, a first shock absorber dial is disposed in at least one of the moving member and the first stop member, and absorbs impact at a time of contact, and a second shock absorber that is disposed in at least one of the moving member and the second stop member, and absorbs impact at a time of contact.

A sheet binding processing apparatus including a processing tray, a sheet positioning device, a first binding device, a second binding device, a driving device which moves the second binding device to a binding position where the sheets positioned by the sheet positioning device are to be bound and to a retracting position for retracting to the outside of the sheets positioned by the sheet positioning device, and a controller which controls the driving device and causes the second binding device to be located at the retracting position when the first binding device binds sheets.

A sheet processing apparatus includes a saddle unit on which a mountain-folded sheet folded along a folding line is accumulated so as to straddle the saddle unit, a staple inserting section disposed above the saddle unit, and a staple receiving section accommodated in the saddle unit. The staple inserting section includes an inserting unit which inserts a staple into the folding lines of the sheets, and holding members disposed on both sides of the inserting unit in a direction parallel to the folding lines of the sheets. The staple receiving section includes a staple receiving unit which receives and bends the tips of the staple inserted by the inserting unit, and supporting members disposed on both sides of the staple receiving unit at positions opposite to the holding members.

A sheet processing device is for binding sheets together. The sheet processing device includes binding units differing from each other in maximum sheet count, the maximum sheet count being a maximum number of sheets that can be bound at a time; a sheet tray configured to hold sheets until all to-be-bound sheets are placed therein, the number of the to-be-bound sheets being a largest one of the maximum sheet counts of the binding units or smaller; and a stacked-sheet-count limiting unit situated in a thickness direction of the sheets held in the sheet tray. The stacked-sheet-count limiting unit is configured to limit the number of sheets held in the sheet tray by varying a distance from a sheet support surface of the sheet tray on which the sheets are placed, depending on one of the binding units by which the sheets held in the sheet tray are to be bound.

An image forming apparatus includes an image forming portion, a fixing portion configured to heat the toner image formed on the sheet by the image forming portion and fix the toner image to the sheet, a folding portion configured to fold the sheet having passed through the fixing portion such that a surface of the sheet to which the powder adhesive is applied is inside, and a bonding portion configured to heat the sheet folded by the folding portion and bond the sheet by the powder adhesive. A relationship of Tmax1>Tmax2 is satisfied, where Tmax1 (° C.) is a highest temperature of the powder adhesive when being heated by the fixing portion and Tmax2 (° C.) is a highest temperature of the powder adhesive when being heated by the bonding portion.

A sheet processing includes a first conveyance path, a buffering portion, a second conveyance path, a conveyance roller pair, a supporting portion, a moving member, a regulating portion, and a processing unit. The buffering portion is configured to superimpose a first sheet and a second sheet on each other in a state of being offset from each other in a sheet conveyance direction. An offset amount, by which a leading end of the first sheet in the sheet conveyance direction projects downstream in the sheet conveyance direction with respect to a leading end of the second sheet in the sheet conveyance direction in a state before the first sheet and the second sheet are discharged onto the supporting portion, is larger than a distance from a sheet contact position of the moving member to the regulating portion in the sheet conveyance direction.

A device for further processing web- or sheet-type stock comprises a further-processing section, in which stock that is supplied on the input side can be processed into printed products. The further-processing section comprises, in the guide path of a processing line through which the stock has run, at least one first combining device relative to the stock path, which can combine one- or multi-layer stock sections to a bundle; a second combining device which can combine the bundles formed by the first combining device to a bundle stack downstream of the first combining device; and a transverse folding device which is arranged functionally downstream of the second combining device and which transversely forms the bundles or bundle stacks relative to the conveying device on the input side when they exit the second combining device. A device for joining several layers is placed in the guide path, such that it can join several or all of the stock sections combined in the first combining device into a bundle, before they are received by the second combining device and is associated with, are arranged downstream of the first combining device. During production of the products, a combined bundle is stapled before it is combined with one or more other bundles and is then transversely folded. In addition, a longitudinal cutting device is provided in the guide path downstream of the transverse folding device.

A printing apparatus includes a control unit configured to control a printing unit to start printing on sheets after confirming that a number of sheets used for printing does not exceed an upper limit number of sheets bindable by a first binding processing in a case where the first binding processing is specified and control the printing unit to start printing on sheets without confirming that a number of sheets used for printing does not exceed an upper limit number of sheets bindable by a second binding processing in a case where the second binding processing is specified.

An image forming apparatus includes, an image forming portion configured to form a toner image on a sheet using printing toner and apply powder adhesive on the sheet, a fixing portion configured to heat the toner image formed on the sheet and the powder adhesive applied on the sheet by the image forming portion and fix the toner image and the powder adhesive to the sheet, and a bonding portion configured to bond the sheet with the powder adhesive by reheating the sheet having been heated by the fixing portion. The bonding portion is arranged above the image forming portion.
