When a second sheet that is different from a first sheet discharged and stacked on a stacking unit is to be stacked on the first sheet, whether or not to apply an alignment process to the second sheet is determined. If it is determined that the alignment process is not to be applied to the second sheet, the second sheet is stacked on the stacking unit. The alignment process is not applied thereto. If it is determined that the alignment process is to be applied to the second sheet, the second sheet is stacked on the stacking unit and the alignment process is applied thereto. |
