Sheet processing apparatus and image forming apparatus provided with the same

摘要

A cover for forming an outer appearance of a stapler unit for performing a stapling process to a sheet bundle serves also as a part of an outer shell of an apparatus body, and the stapler unit is provided selectively to the apparatus body movably between a position for stapling the sheet bundle and a position for replacing staple cartridges, to thereby make it possible to readily perform a jam process or staple replacement.
