A sheet discharge apparatus includes a discharge device for discharging sheets, a storage device for receiving the sheets discharged by the discharge device, alignment reference members for aligning at least one side of the sheets discharged to the storage device, rotating bodies (belt unit) that contact the sheets at a predetermined position on the storage device to move the sheets to the alignment reference members, a support device for supporting the rotating bodies to move freely between an activating position that contacts the sheets at the predetermined position and a retracted position away from the sheets at the predetermined position, and a control device for controlling the support device to position the rotating bodies at the retracted position when the sheets reach the predetermined position before a trailing edge of the sheets in a discharge direction is discharged to the storage device by the discharge device.
