A sheet processing apparatus includes a pressing unit including a first pressing member and a second pressing member. The pressing unit is configured to press a fold in a folded sheet bundle by holding the fold between the first pressing member and the second pressing member. The sheet processing apparatus also includes a moving unit configured to move a pressing position of the pressing unit in a direction of the fold in the sheet bundle; and a position changing unit configured to change relative positions of the first pressing member and the second pressing member in the direction of the fold in the sheet bundle.

A saddle stitching binding device includes an additional folding roller unit that presses a fold line portion of a folded sheet bundle and performs additional folding, and a unit movement mechanism that causes the additional folding roller unit to reciprocate in the width direction of the sheet bundle. The saddle stitching binding device further includes a sheet supporting device that is located on a movement path of the additional folding roller unit and supports the lower surface side of the sheet bundle when the sheet bundle after pressed is conveyed to the downstream side. In the saddle stitching binding device, a supporting position at which the sheet supporting device supports the sheet bundle and a retreat position at which the sheet supporting device permits the additional folding roller unit to move are set to the sheet supporting device.

A sheet processing device includes: a conveying module that conveys a folded sheet; and a pressing module that presses a folded part of the folded sheet by rotating about a direction orthogonal to a sheet conveying direction of the conveying module as a rotation axis. The pressing module includes a projecting part arranged in a certain range in a direction of the rotation axis along a circumferential surface about the rotation axis. The projecting part is formed to be symmetric with respect to a middle part of the rotation axis in the direction of the rotation axis, and the projecting part arranged on one side from the middle part along the direction of the rotation axis are formed such that a position of the projecting part in a rotational direction of the circumferential surface varies along the direction of the rotation axis.

A sheet processing apparatus includes: a second conveying roller pair that receives and conveys a sheet conveyed by a first conveying roller pair; a first folding roller pair that forms a first fold on the sheet; and a first rotation unit capable of rotating the second conveying roller pair and the first folding roller pair. One roller of the second conveying roller pair and one roller of the first folding roller pair are a common roller shared therebetween. The second conveying roller pair causes the sheet to be deflected and guided to the first folding roller pair, and the first folding roller pair forms the first fold on the deflected sheet by rotating the first rotation unit in a certain direction in a state in which the sheet is held by the first conveying roller pair and the second conveying roller pair.

A sheet processing device includes a conveying unit, a presser, an end detector, and a setting unit. The conveying unit conveys a sheet having a crease formed therein. The presser presses the crease in the sheet. The end detector detects an end in a conveying direction of the sheet at a position upstream of the presser in the conveying direction. The setting unit sets a crease position where the crease is to be formed. Upon detection of the end in the conveying direction, the conveying unit conveys the sheet to a position where the crease faces the presser, on the basis of the crease position set by the setting unit. The presser presses the crease in the conveyed sheet.
