Sheet processing apparatus and image forming apparatus

摘要

A sheet processing apparatus includes pairs of rollers being sheet conveying units that convey recording sheets that are sheet media, a binding tray in which a plurality of recording sheets conveyed by the pairs of rollers are stacked and the recording sheets are retained as a paper bundle, and a stapler being a binding unit that performs a binding process on the paper bundle retained in the binding tray. Target positions on the paper bundle are adjusted by moving both of two jogger fences in an R direction to move the paper bundle in the sheet width direction so as to displace the paper bundle with respect to the stapler.
