To suppress the bending of sheets, a sheet conveying apparatus includes a sheet conveying portion including an abutting portion for abutting against an end portion of the sheet supported by a supporting portion and which conveys the sheet being abutted against the abutting portion by moving in a predetermined moving direction, and a pressing portion which is provided on the sheet conveying portion such that the pressing portion is movable in a thickness direction of the sheet and which presses the sheet toward the supporting portion. The pressing portion includes an inclined portion arranged to be closer to the supporting portion at an upstream side than a downstream side, and a contacting portion configured to contact a surface of the sheet being abutted against the abutting portion to press the sheet to the supporting portion at a position distant from the abutting portion.

According to an embodiment, there is provided a sheet processing apparatus includes a stacking unit that stacks a sheet conveyed thereto; a first alignment unit that aligns the sheet or a bundle of sheets stacked in the stacking unit in a sheet conveying direction; a second alignment unit that aligns the sheet or the bundle of sheets stacked in the stacking unit in a direction orthogonal to the sheet conveying direction; a pressing unit that presses the bundle of sheets at an end portion thereof on a predetermined one side; and a control unit that causes at least one of the first and second alignment units to execute an alignment operation during a press operation of the sheet or the bundle of sheets performed by the pressing unit.

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 control apparatus performs binding processing for binding a plurality of sheets without using a staple to enable a user to easily separate a sheet from a sheet bundle after the binding processing. The printing control apparatus causes a binding unit to perform a binding processing for binding a plurality of sheets without using a staple, and then controls the binding unit to perform a binding processing for binding the plurality of sheets and a sheet different from the plurality of sheets.

A sheet takeout device has a feeding section, a takeout section, an air blowout section. The feeding section has a bottom wall with which one sides of a plurality of stacked sheets come in contact, and holds the plurality of sheets. The takeout section takes out the tipmost sheet by suction from the plurality of sheets, and sends out the tipmost sheet in a sending direction. The air blowout section blows out air toward between the one side of the sheet to be sucked by the takeout section and the one side of the sheet next to this sheet. The air blowout section has a first air blowout portion arranged at a position corresponding to a forward portion of the sheet in the sending direction, and a second air blowout portion arranged at a position corresponding to a backward portion of the sheet in the sending direction.
