1. A sheet processing apparatus comprising:
a discharge unit configured to discharge, from a discharge port, a sheet bundle transported along a transport path;
a loading unit onto which the sheet bundle that has been discharged is loaded;
an abutting unit disposed forward from the discharge port in a discharge direction of the sheet bundle so that the abutting unit abuts with a top surface of the sheet bundle that has been discharged;
a support unit that is protrusible from and retractable into the discharge port and is configured to protrude to an underside of the sheet bundle temporarily to support the sheet bundle when the sheet bundle is discharged; and
a control unit configured to control movement of the support unit such that the support unit reaches a position of the abutting unit after the sheet bundle abuts with the abutting unit.
