To reduce adhesion of unintended toner to a cover of a booklet.SOLUTION: The holding means holds a sheet bundle composed of one or a plurality of sheets on which a toner image by adhesive toner is formed in an adhesive area. The pressurizing unit applies pressure to the sheet bundle, and the heating unit applies heat to the toner image of the adhesive toner formed in the adhesive area of the sheet. The heating means executes heating processing every time the sheet bundle is stacked on the holding means. A storage elastic modulus of a toner image formed on a target sheet closest to the heating means in the N-1th sheet bundle is higher than a storage elastic modulus of a toner image formed on another sheet closest to the heating means in each of the first sheet bundle to the N-2th sheet bundle.SELECTED DRAWING: Figure 8

A booklet making apparatus comprises a heating and pressing unit that heats and presses an adhesive layer in a state where a plurality of sheets on which the adhesive layer has been formed are layered. The heating and pressing unit includes a pressing plate, a heating body that heats the pressing plate, a reception member, and a pressing mechanism. A booklet is made by heating and pressing the adhesive layer while holding the plurality of sheets on which the adhesive layer has been formed between the pressing plate and the reception member. The pressing mechanism applies pressure to the plurality of sheets held between the pressing plate and the reception member by pressing the pressing plate without applying a force to the heating body.

A sheet processing apparatus includes a center folder and a back pressure binder. The center folder performs center folding on a sheet bundle including a plurality of sheets. A back crimp binder includes a back former and a crimp binder. A back former forms a back on the sheet bundle subjected to the central fold. A crimp binding device performs crimp binding on the sheet bundle subjected to the central fold.

A sheet processing apparatus includes a center folder, and a back-crimp binder. The center folder performs a center folding on a sheet bundle including multiple sheets. The back-crimp binder includes a back-portion former and a crimp binder. The back-portion former forms a back portion on the sheet bundle subjected to the center folding. The crimp binder performs a crimp binding on the sheet bundle subjected to the center folding.

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.

Provided is a three-edge cutting machine that switches between a mode in which cut processed books are gathered in a constant number and moved out, and a mode in which cut processed books are sequentially gathered. The three-edge cutting machine is provided with a cutting unit (1), a book gathering unit (3), a moving-out unit (2), and a conveying mechanism (4) that conveys cut processed books (BK) to the book gathering unit. When the book gathering unit is operated in a handover mode, each time a book is placed on a shelf, the shelf is lowered by an amount corresponding to the thickness of the book, and when the books on the shelf reach a prescribed amount, the shelf is moved to the height of an inlet (2a) of the moving-out unit so as to drive a roller conveyor to feed the books to the moving-out unit, after which the shelf is moved to the height of an outlet (1a) of the cutting unit. When the book gathering unit is operated in a gathering mode, during a period in which a prescribed amount of books is gathered on the shelf, each time a book is placed on the shelf, the shelf is lowered by an amount corresponding to the thickness of the book.

Provided is a heater that performs heat processing when a sheet bundle is stacked on a holding plate. A storage elastic modulus of a toner image by an adhesive toner formed on a sheet of interest closest to the heater in an N−1-th sheet bundle second closest to the heater in a booklet is greater than a storage elastic modulus of a toner image by the adhesive toner formed on any sheet included in another sheet bundle located farther from the heater than the N−1-th sheet bundle in the booklet.
