A third pressing roller includes a third pressing surface that presses the fold end portion of the sheet bundle between the lower pressing plate and the upper pressing plate. The third pressing roller moves in between the lower pressing plate and the upper pressing plate. The third pressing roller or the pressing unit moves so that the third pressing surface of the third pressing roller presses the fold end portion at a predetermined position based on a tip of the fold end portion.
