<p>PROBLEM TO BE SOLVED: To prevent mutual contact of recording paper, prevent a stain of the recording paper, and refeed it safely and reliably by forming/fixing an image on/to the recording paper, carrying the recording paper refed in a copying device by a prescribed distance by a recording paper branching means, and movably supporting and guiding plural recording paper to be refed to a transfer part by stopping-reversing them while sandwiching one ends as they are. SOLUTION: A toner image is transferred to recording paper P, and when a double sided copy is performed after being thermally fixed, a carrying passage is switched by a recording paper branching member 110, and it is carried to a recording paper accumulating reversing part 302. It is supplied between a pair of roller groups 301, and rotation is started in the carrying direction, and the recording paper P is dropped on a stack part 305 while sandwiching it. In that case, the tip of the dropping recording paper P is detected by a detecting member S8, and a pair of roller groups 301 are stopped for a constant time by rear end detection of a detecting member 56. When the prescribed number of recording paper P are housed, a pair of roller groups 301 reversely rotate, and after the tip is detected by a detecting member 57, it is carried to a position of a regist roller 115, and an image is transferred to the reverse.</p> |
