Claim 5:
6. The sheet processing apparatus according to claim 1, wherein
the fold rotating body pair has first peripheral surfaces each being at a location at a constant distance from a center of the fold rotating body and brought into contact with each other at the nip part to allow fold processing and second peripheral surfaces each being at a location at a distance from the fold rotating body center smaller than the distance between the first peripheral surface and the fold rotating body center and not brought into contact with each other at the nip part, and
the control unit controls the rotation of the fold rotating body pair such that the first peripheral surfaces face each other at the nip part of the fold rotating body pair when fold processing is applied to the sheet and that the second peripheral surfaces face each other when the first fold position at which the first fold line has been formed passes through the nip part.
