A medium processing apparatus includes a conveying unit, a liquid applier, and a crimper. The conveying unit conveys a medium in a conveyance direction. The liquid applier applies liquid to the medium conveyed by the conveying unit. The liquid applier includes a presser and a liquid application member. The presser presses the medium. The liquid application member contacts and is separated from the medium while the presser presses the medium. The crimper presses and deforms a plurality of media including the medium to which the liquid is applied by the liquid applier, to crimp and bind the plurality of media.

An image forming apparatus at least comprising: first image forming means for forming a first adhesive layer of a first toner on a sheet; and second image forming means for forming a second adhesive layer of a second toner on the first adhesive layer, adhesive image patterns are formed from the first and the second adhesive layer, the image forming apparatus further comprising specific booklet bonding means, wherein at least both the first and the second adhesive layer are formed on one of a first sheet and a second sheet that face each other in the sheet bundle, at least the first adhesive layer is formed on the other of the first sheet and the second sheet, and G1>G2 is satisfied, where G1 denotes a storage elastic modulus of the first toner, and G2 denotes a storage elastic modulus of the second toner.

A method operates a facility, which serves for the continuous production of multiple gang runs for forming individual signatures or signature packs from which type-specific print products are made in a downstream print further processing machine. An endless web is the basis for the formation of these multiple gang runs. The endless web, in the non-folded state, is imparted complementary handling by facility-internal means according to the following criteria: i) in a 2-gang run, the individual signatures or the folded signature packs are only deflected in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station; and ii) in a 3 or 4-gang run, the individual signatures or the folded signature packs are additionally folded in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station.

In a case where a region of a heating pressurization unit in a longitudinal direction of the heating pressurization unit where the heating pressurization unit heats and pressurizes a sheet of a maximum size is a first region, and a region of the heating pressurization unit in the longitudinal direction where the heating pressurization unit heats and pressurizes a sheet of a minimum size is a second region, and a region of the heating pressurization unit inside the first region and outside the second region in the longitudinal direction is a third region, the heating pressurization unit heats and pressurizes the sheet of the maximum size with a pressurization force profile having a minimum value in the longitudinal direction at a position in the third region or a position of an end portion of the second region adjacent to the third region.

A sheet processing apparatus includes: a conveyance unit configured to convey a sheet to a loading board; a bonding unit configured to execute bonding processing for bonding together a plurality of loaded sheets loaded on the loading board, with use of an adhesive image formed on the plurality of loaded sheets; and a control unit configured to control the bonding processing executed by the bonding unit in order to create a bundle of sheets from a designated number of sheets designated by a job, wherein the control unit is further configured not to execute the bonding processing with respect to the plurality of loaded sheets in a case where a thickness of the plurality of loaded sheets exceeds a first threshold.

A binding processing device includes: a paper support unit that supports a paper bundle; a pressing unit that presses the paper bundle; and a binding processing unit that performs binding processing by moving binding teeth toward the paper bundle to apply pressure to the paper bundle, the binding processing unit moving from a binding position of the paper bundle while the paper bundle is being pressed by the pressing unit.
