PROBLEM TO BE SOLVED: To provide an image forming apparatus which can eject a plurality of copies with each identifiable on an ejection tray in a simple structure without connection to a sorter. SOLUTION: A pre-ejection roller 13c1 and a post-ejection roller 13c2 lined up in the axial direction and a pre-ejection roll 13d1 and a post-ejection roll 13d2 which are in pressurized contact with the rollers 13c1 and 13c2 and rotated following the rollers 13c1 and 13c2 are tandemly-arranged in the axial direction. The pre-ejection roller 13c1 is driven by a motor 16a1 and the post-ejection roller 13c2 is driven by a motor 16a2. When a back end of recording paper P is separated from a nip part in a fixing part, the pre-ejection roller 13c1 and the post-ejection roller 13c2 are driven at different circumferential velocities and the recording paper P is ejected inclined to a reference ejecting direction. By switching the speed relationship between the pre-ejection roller 13c1 and the post-ejection roller 13c2 every time one piece of copy is finished, the plurality of pieces of copies are ejected each inclined in different directions to the reference ejecting direction onto the ejection tray, making identification easy for the copies which are in the plurality of number of pieces.
