Abstract

A sheet post-processing device includes a placement unit for placing a sheet discharged from an image forming apparatus; a discharging unit for successively discharging the sheet on the placement unit; and an offset unit for shifting an edge of a stitching sheet from an edge of a non-stitching sheet on the placement unit by a predetermined distance depending on whether the sheet discharged on the placement unit is subjected to a stitching process. A stitching unit stitches only the edge portions of the stitching sheets in a stack in a state that the edges of the stitching sheets are shifted from the edge of the non-stitching sheet by the offset unit.
