ABSTRACT:
The present invention provides a sheet stacking apparatus which has a pair of lower discharge rollers which discharges a sheet, a processing tray which stacks the sheet discharged from the pair of lower discharge rollers, a trailing end stopper which aligns the trailing end portion in the conveying direction of the sheet bundle stacked on the processing tray, and pull-in paddles which drop the sheet discharged from the pair of lower discharge rollers on the processing tray and conveys the sheet to abut against the trailing end stopper where the pull-in paddles rotate at a first rotating speed so that the sheet discharged from the pair of lower discharge rollers is dropped on the processing tray and the pull-in paddles rotate at a second rotating speed, slower than the first rotating speed, so that the sheet abuts against the trailing end stopper.
