A sheet processing apparatus (100) includes a first member (1012) having a first concavo-convex portion (1013) in which pluralities of concavities and convexities (10214) are provided, a second member (1029) having a second concavo-convex portion (10212) in which pluralities of concavities and convexities (10210) are provided and clamping a sheet bundle (PA) together with the first concavo-convex portion (1013) of the first member (1012), and a supporting portion (10211) supporting at least one of the first and second members (1012, 1029) turnably centering on a turning center (A). The first concavo-convex portion (1013) is configured such that a distance (L1) between an end on the turning center side of one convex portion among the pluralities of concavities and convexities (10214) and the turning center (A) is different from a distance (L2) between an end on the turning center side of another convex portion and the turning center (A). |
