The apparatus has a first paper ejection roller which is provided at a terminal end section of a paper transport path, a second paper ejection roller which is provided such that it is urged into contact with the first paper ejection roller to switch back printed paper in a double side printing mode in cooperation with the first paper ejection roller, a third paper ejection roller which is provided in a position opposite to the second paper ejection roller such that it is urged into contact with the first paper ejection roller to eject paper on which printing has been completed in the double side printing mode onto an ejected paper tray in cooperation with the first paper ejection roller, and a stopper for preventing the paper ejected onto the ejected paper tray from being caught between the first and second paper ejection rollers and between the first and third paper ejection rollers.
