Abstract
A sheet stacking apparatus includes a sheet discharge tray that holds a discharged sheet and that moves up and down, and a sheet discharge roller that is located above the sheet discharge tray and that discharges the discharged sheet to the sheet discharge tray. The sheet discharge tray receives the discharged sheet from the sheet discharge roller at a standard sheet receiving position which is located at a predetermined downward distance away from the sheet discharge roller. The sheet discharge tray moves down to a position which is lower than the standard sheet receiving position for a predetermined distance and receives at least a next sheet at the position, when a stacked amount of sheets on the sheet discharge tray reaches a predetermined stacking amount.
