Abstract

This invention relates to a sheet postprocessing apparatus for executing postprocessing including a punching process, folding process, binding process, and the like, midway along a sheet convey path, for sheets discharged from an image forming apparatus, and a folding method. This sheet postprocessing apparatus includes a sheet folding section having the first and second folding sections which are arranged in series in a sheet convey direction to execute folding processes for sheets. The sheet folding section is configured such that the first folding section performs the first folding process in a Z-fold process, the first folding process in an internal three-fold process, and a center folding process with an image-transferred surface facing outside, and the second folding section performs the second folding process in the Z-fold process, the second folding process in the internal three-fold process, and a center folding process with an image-transferred surface facing inside.
