PURPOSE:To prevent a blank paper from being mixed in copying papers to which copying is performed by ejecting the copying paper fed in a copying machine main body as a blank paper when the jamming of fed paper occurs on an intermediate tray where the paper is temporarily stacked at the time of performing both-side copying. CONSTITUTION:The paper jamming occurs in a recirculating document feeder(RDF) 2, the paper to which an image is transferred is ejected to the outside of the copying machine 1 through a fixing roller 41 and a paper ejecting roller 43. The paper which is fed so that the image of an (n-1)th document is transferred there passes a drum 34 in a state where it is blank. Then, a flapper 44 moves and the paper which is blank gets in a both-side unit 7 and is stacked on the intermediate tray. Thus, the fed copying paper is prevented from being stacked on a sorter, etc., as the blank paper. |
