A sheet processing apparatus comprises: a first member having a first concavo-convex portion in which a plurality of concavities and convexities are provided; a second member having a second concavo-convex portion in which a plurality of concavities and convexities are provided and clamping a sheet bundle together with the first concavo-convex portion of the first member; and a support unit supporting at least one of the first and second members to be turned around a turning center. The first concavo-convex portion is configured such that a distance between an end on the turning center side of one convex portion among the concavities and convexities and the turning center is different from a distance between an end on the turning center side of another convex portion and the turning center. |
