Sheet processing apparatus and image forming apparatus

摘要

There are provided a sheet processing apparatus which can perform a punching process while suppressing decrease in productivity, and an image forming apparatus including the sheet processing apparatus. In a third carry-in route R3 branching from a first carry-in route, a discharge roller and a buffer roller convey a sheet for which the punching process has been performed by a punching unit, so that an upstream end in a sheet conveyance direction of the sheet for which the punching process has been performed precedes an upstream end in the sheet conveyance direction of a succeeding sheet following the sheet for which the punching process has been performed.
