摘要

A sheet stapling apparatus (400) includes a storage unit (406) for storing sheets ejected out from an image forming apparatus (200), and a stapling unit (410) for stapling the sheets stored in the storage unit (406). The sheet stapling apparatus (400) can execute a first bending process for bending the feet of a staple which were pierced through the sheets to the inside and a second bending process for bending the feet of the staple which were pierced through the sheets to the outside. In the facsimile mode or the printer mode, the second bending process is executed. $$
