The present invention provides a post process control apparatus including a post processing unit configured to perform post processing on a printed sheet printed in accordance with a job, and a method for controlling the same, where the post process control apparatus and the method of controlling the same obtain a number of sheets in one copy of printed sheets instructed by the job, control the post processing unit to, if the obtained number of sheets in one copy is singular, execute the post processing in one batch on printed sheets corresponding to a plurality of copies, and to control the post processing unit to, if the obtained number of sheets in one copy is plural, execute the post processing individually by printed sheets corresponding to one copy.

A post processing apparatus includes: a reader that reads paper on which an image is formed by an image forming apparatus to acquire a read image; a post processor that performs post processing on the paper; and a hardware processor that detects a position of an edge of the paper and a position of the image from the read image acquired by the reader, and controls a post processing position in the post processor on the basis of the position of the edge of the paper and the position of the image detected.

A sheet processing apparatus includes a processing unit, a sheet discharge unit, a determination unit, and a control unit. The processing unit performs crease processing on a sheet. The sheet discharge unit discharges a sheet having been subjected to the crease processing by the processing unit. The determination unit determines whether a number of the discharged sheets having been subjected to the crease processing exceeds a predetermined number of sheets. The control unit performs control to cause the discharge unit to discharge a sheet. In a case where the determination unit determines that the number of the discharged sheets having been subjected to the crease processing exceeds the predetermined number of sheets, the control unit performs control to cause the discharge unit to not discharge sheets having been subjected to the crease processing onto the discharge destination.

A sheet processing device that bonds sheets to one another and then folds a resultant sheet bundle. The sheet processing device includes a stacker section that sequentially stores sheets moved thereto, an adhesive-binding unit that applies an adhesive onto sheets sequentially stored in the stacker section one by one in a sheet moving direction to bond the sheets to one another, a moving member that moves the sheets to an application position of the adhesive-binding unit, and a folding processing section that folds a sheet bundle formed by the bonded sheets at a predetermined folding position. When the number of sheets to be bonded by the adhesive-binding unit applying the adhesive onto the sheets exceeds a predetermined number, the adhesive is applied at two positions separated from each other across the folding position.

A sheet processing apparatus comprising: a scoring unit which scores a sheet; a folding unit which folds a sheet bundle including a plurality of sheets; a pressing unit which presses a folded part of the sheet bundle folded by the folding unit; and a controller which determines, based on information on the sheet bundle, whether the scoring unit scores the sheet included in the sheet bundle to be folded and whether the pressing unit presses the folded part of the sheet bundle.

A printing system comprises: a printing unit configured to print an image on a sheet; and a control unit configured to control to perform creasing at a first pressure at a portion, corresponding to an edge of a spine cover, of the sheet on which the printing unit has printed the image, and perform creasing at a second pressure different from the first pressure at a portion of the sheet that corresponds to a hinge.

A control portion of an image forming apparatus creates an image list for performing the perfect-binding imposition of the images of the pages on the sheets so that the scores formed on the sheets are on the external surface of the center-folded sheets, for the sheets each having a size twice the size specified as each of the sheets on which the images of the book body are to be formed, when a book-body stacking portion accommodates the sheets center-folded by a folding portion along scores formed for every sheet from a predetermined direction by a scoring portion for each of the sheets having the images formed thereon by the image forming portion, and a bookbinding portion uses a glue-on cover to perform case binding of a bundle of the sheets glued to the side of the spine.

A printing system includes a control unit configured to control an image forming unit to form an image on a sheet based on print setting information included in received job setting information, control a post-processing unit to execute a post-process corresponding to a designated type, and control a creasing unit.

A sheet folding apparatus for performing folding processing on a sheet in a transporting direction from a carry-in entrance toward a carrying-out exit, has a first transport path for guiding the sheet without performing folding processing; a second transport path for performing folding processing on the sheet; a third transport path for guiding the folded sheet towards the carrying-out exit; and a folding processing device disposed in the second transport path to fold the sheet. The second transport path has a path end portion for guiding the sheet to adjust a folding position of the sheet, a nip point to nip the sheet for folding, and a folded sheet guide path for guiding the folded sheet. The first transport path is arranged between the path end portion of the second transport path and the folding processing device.

An image forming apparatus includes a first development part provided with an image forming developer containing image forming pigments and image forming macromolecular compound, a second development part provided with a bonding developer containing bonding macromolecular compound, a transfer part transferring the image forming developer to a surface of a medium, and a fuser part fusing the image forming developer to the medium. Wherein heating temperature T1 ( C.) for the image forming developer by the fuser part and heating temperature T2 ( C.) for the bonding developer by the fuser part satisfy a condition expressed by Eq. (1) below, and solubility parameter 1 of the image forming macromolecular compound and solubility parameter 2 of the bonding macromolecular compound satisfy a condition expressed by Eq. (2) below.
