A folding apparatus includes a folding device to fold a sheet bundle, an additional folding device, a conveyer, and control circuitry. The additional folding device includes a pressure roller disposed downstream from the folding device in a sheet conveyance direction and configured to press the sheet bundle after the folding device folds the sheet bundle and a sheet support member disposed opposite the pressure roller via the sheet bundle. The conveyer conveys the sheet bundle to a position at which the additional folding device presses the sheet bundle and hold the sheet bundle at the position. The control circuitry causes the additional folding device to perform additional folding processing on a first position of the sheet bundle, the conveyer to move the sheet bundle to a second position different from the first position, and the additional folding device to perform the additional folding processing at the second position again.

A sheet processing apparatus includes a rotatable pressing member, a guide, and a contact member. The rotatable pressing member includes a pressing portion that is disposed in a predetermined range in a rotation direction of the pressing member to press a folded portion of a sheet. The guide is disposed opposite the pressing member. The contact member contacts the guide and is rotatably disposed at at least one end of the pressing member in an axial direction of the pressing member.

A conveying device that conveys a sheet bundle with a flattened back-face portion includes a first conveying unit, a driving unit, and a second conveying unit. The first conveying unit retracts to a position where no driving force is exerted on the sheet bundle before a leading end of the sheet bundle formed in a flat spine shape enters, and abuts on the sheet bundle to exert conveying force after the leading end of the sheet bundle passes a conveying position. The driving unit moves the first conveying unit to retract to the position and to abut on the sheet bundle. The second conveying unit is positioned on an upstream side of the first conveying unit in a sheet bundle conveying direction and conveys the sheet bundle towards the first conveying unit.

An spine formation device includes a sheet conveyer to transport a bundle of folded sheets with a folded portion of the bundle of folded sheets forming a front end portion, a sandwiching member to sandwich and squeeze the bundle of folded sheets in a direction of thickness of the bundle of folded sheets, and a spine formation unit disposed downstream from the sandwiching member in the sheet conveyance direction, to flatten the folded portion of the bundle of folded sheets held by the sandwiching member. The spine formation unit presses the folded portion of the bundle of folded sheets projecting a predetermined length from the sandwiching member in the sheet conveyance direction in a reverse direction of the sheet conveyance direction while moving in a direction perpendicular to a longitudinal direction of the folded portion of the bundle of folded sheets.

A spine formation device includes a sheet conveyer to transport a bundle of folded sheets, a pressing unit including a first pressing member movable according to a pressing load in a pressing direction perpendicular to the sheet conveyance direction to press opposed sides of the front end portion of the folded sheets and a second pressing member attached to the first pressing member, to press the front end portion of the folded sheets, and a spine formation member disposed at a predetermined distance from the pressing unit. The second moves in the sheet conveyance direction in conjunction with the first pressing member moving in the pressing direction and presses the folded portion of the bundle of sheets with a predetermined spine-forming load against a contact surface of the spine formation member, thereby forming a spine of the bundle of sheets.

A spine formation device includes a sheet conveyer, a presser, and a spine formation member. The sheet conveyer conveys a bundle of folded sheets with a folded portion of the bundle of sheets forming a front end portion of the bundle of sheets. The presser is disposed downstream from the sheet conveyer in a sheet conveyance direction in which the sheet conveyer conveys the bundle of sheets. The presser is movable to press opposed sides of the front end portion of the bundle of sheets. The spine formation member is movably disposed downstream from the presser in the sheet conveyance direction. The spine formation member includes a groove portion that contacts and positions the bundle of sheets to define an amount by which the bundle of sheets protrudes from the presser and a spine formation face that forms a spine at the folded portion of the bundle of sheets.

A sheet finisher of the present invention includes jogger fences for jogging sheets sequentially stacked in a stapling section, and a stapler for stapling the sheets together. A CPU (Central Processing Unit) controls a jogger motor such that the jogger fences each move to a first position, a second position, and a third position in accordance with the width of sheets in a direction perpendicular to the direction of sheet conveyance. The first position is remote from the edge of a sheet stack in the direction of the width by a preselected amount. The second position is closer to the edge than the first position by a preselected amount and slightly overlaps the edge. At the third position, when the stapler staples the sheet stack, the jogger fence substantially contacts the edge in accordance with the width.
