ABSTRACT:
A digital copy machine includes an image reading unit IR, an image memory, an image formation unit PRT, and a circulation type sheet transportation mechanism having a transportation path of a length that can accommodate n (n.gtoreq.2) sheets for reversing the side of the sheet having a copy image formed on one side to the opposite side and refeeding the same to a copy position. In duplex copying using at least n sheets, the timing of feeding the first sheet is set so that the n-th sheet arrives at the copy position only after the time when the copy of an original image of the (2n-1)th page can be initiated in order to set the number of circulating sheets to n.
