摘要

A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section.
