Claim 8:
9. A method of operating a sheet post-processing apparatus, the apparatus comprising a binder configured to apply binding to a sheet, and a tray on which the sheet applied with the binding is stacked, the method comprising:
pushing a side surface of a first sheet bundle of the sheet applied binding, and moving in a sheet width direction orthogonal to a discharge direction and performing a first shift operation in which the first sheet bundle is deviated to a first position during discharge of the first sheet bundle to the tray;
pushing a side surface of a second sheet bundle of the sheets applied binding and moving in a direction opposite to the first shift operation and performing a second shift operation in which the second sheet bundle is deviated to a second position during discharge of the second sheet bundle to the tray;
causing the operation of moving a shifter to the first position and the operation of moving the shifter to the second position by dividing the number of times for the operation into a plurality of times;
temporarily stopping the operation of moving during discharge of the sheet to the tray; and
causing the time for temporarily stopping the operation of moving to be longer as a length that the shifting pushes the sheet in the sheet width direction becomes shorter.
