ABSTRACT:
A copy machine having an image forming section includes a paper transport passage to such section, a turn-over guide portion which turns over the sheet formed and recorded with an image on its one surface for feeding-in, and a sheet return for returning the sheet formed and recorded with the image on its one surface, from a paper discharge section towards the turn-over guide portion. And, with each one sheet or n (n.gtoreq.2) sheets being set as one group, each of the sheets recorded on its one surface per each group, is returned to the paper feeding transport passage for effecting image formation and recording onto its other surface. The sheet returning speed is set to be either faster than the ordinary transport speed at the image forming section or to be variable so as to eliminate a loss in time during recording to the other surface of the sheet after recording onto the one surface thereof.
