The present invention holds the source document feeding direction downstream edge of a printed sheet ejected above a source document feed tray by means of a top ejection platform functioning as a printed sheet holding section in an area apart from source document feed rollers functioning as a source document feeding section. As a result, a printed sheet ejected onto top ejection platform is not fed automatically by source document feed rollers. Therefore, a printed sheet that has undergone image formation can be ejected without obstruction above source document feed tray of an automatic document feeder, checking and removal of a printed sheet are facilitated, and convenience is improved.
