Abstract: Disclosed is an image forming apparatus that includes an image forming section, a conveyance section, a position detecting section, an abnormality detecting section and a control section. When determining as the first determination that it is possible to eject each of the paper sheets and/or the image-formed paper sheets outside and determining as the second determination that it is necessary to re-output the new image-formed paper sheet, the control section incompletely ejects each of the retention paper sheets, remaining within the image forming apparatus, outside from the ejection opening. By controlling the apparatus as above-mentioned, even in a case where it is impossible to eject the concerned paper sheet onto a separate tray, it becomes possible to prevent the retention paper sheet from remaining at an apparatus-inner position, from which it is difficult for the user to remove the retention paper sheet concerned.
