There is provided a technique in which while the occurrence of a sheet jam is avoided, a pair of folding rollers for a folding process and a stapler for a staple process can be disposed to be close to each other, and a contribution can be made to the improvement of productivity. A staple unit is provided which performs a staple process to a bundle of sheets transported to a specified staple position in a sheet transport path, and staples the bundle of sheets by causing a press unit that presses a sheet surface of the bundle of sheets when the staple process is performed to cooperate with a reception unit that is disposed to face an inside of the sheet transport path through a hole provided in an inner wall of the sheet transport path and receives the bundle of sheets pressed by the press unit, and a vicinity of an upstream side edge of the reception unit in a sheet transport direction on the sheet transport path is covered by an elastic member supported by one of a wall surface of the sheet transport path and the reception unit.

A sheet folding apparatus includes a fold unit which folds a center of a sheet bundle to form a fold line, and a reinforce roller which moves along the fold line while applying pressure to the fold line to reinforce the fold line. The reinforce roller includes plural sub-rollers which are concentrically coupled to each other in a rotation axis direction, and the respective sub-rollers apply different pressures to the fold line.

Provided herein is a sheet processing apparatus including a processing apparatus and a saddle unit. The saddle unit moves from a position inside the processing apparatus, along a direction orthogonal to a sheet transport direction, to a position outside the sheet processing apparatus. When the saddle unit is in the position outside the processing apparatus, a first transport guide is open to expose the outside of a first sheet transport path, and a second transport guide is open to expose the inside of the first sheet transport path. The saddle unit also includes a stapler, a folding blade and a pair of folding rollers, the first sheet transport path, and a second sheet transport path.

A saddle unit provided with a fold-enhancing unit for performing fold enhancement of sheets of paper folded in the middle. The fold-enhancing unit includes a fold-enhancing roller mechanism which performs the fold-enhancing operation in the direction orthogonal to the sheet carrying direction. The fold-enhancing roller mechanism includes a fold-enhancing roller pair that pinches and presses a bundle of sheets at a nip. The roller guide pair provided in the fold-enhancing roller mechanism guides the sheets of paper to the nip of the fold-enhancing roller pair when enhancing the fold of the sheets of paper. The saddle unit changes one or both of the number of times and the velocity of the reciprocating movement according to one or both of the number of sheets of paper and the quality mode which is entered and set by the user from the operation panel of an image forming apparatus or job-set by the personal computer by a user.

There is provided a technique in which a retracting operation of a bundle of sheets from a stapler after a staple process can be stably performed irrespective of the number of sheets constituting the bundle of sheets or the transport resistance. When the bundle of sheets subjected to the staple process is moved by a stacker in a direction of retracting from the stapler, an alignment roller is caused to come in contact with the bundle of sheets held by the stacker and to assist the movement of the bundle of sheet.
