Abstract
The present invention provides a sheet processing apparatus and an image forming apparatus which can achieve reduction of running cost. A notch part forming portion 400A including a punch 403 and a die 404 forms plural notch parts in an end part of a sheet bundle folded by a sheet folding portion. A discharge roller pair 402a and 402b turns back the notch parts to bind the sheet bundle. As a result, the sheet bundle can easily be opened and the reduction of the running cost can be achieved because stapling is not performed.
