Classification: CPC B | IPC B

Claim 0:
1. A sheet post-processing apparatus comprising:
a binder configured to apply binding to a sheet;
a tray on which the sheet applied with the binding is stacked;
a shifter configured to:
push a side surface of a first sheet bundle of the sheets applied binding and move in a sheet width direction orthogonal to a discharge direction and perform 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; and
push a side surface of a second sheet bundle of the sheets applied binding and move in a direction opposite to the first shift operation and perform 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; and

a controller configured to:
cause the operation of moving the 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 of moving into a plurality of times;
temporarily stop the operation of moving during discharge of the sheet to the tray; and
cause the time for temporarily stopping the operation of moving to be longer as a length that the shifter pushes the sheet in the sheet width direction becomes shorter.
