ABSTRACT:
According to the invention, a sheet finisher has a folding mechanism, a discharging mechanism, a stacking mechanism, and a slip amount calculator. The folding mechanism forms a folding line by folding a sheet which an image forming unit discharges. The discharging mechanism discharges the sheet including the folding line which the folding mechanism forms. The stacking mechanism stacks the sheet which the discharging mechanism discharges. The slip amount calculator outputs a fullness state of the stacking mechanism to the image forming unit, if a slip amount of the discharging mechanism exceeds a threshold.
