PROBLEM TO BE SOLVED: To prevent the transporting defect of a recording paper by preventing the occurrence of a curling, when the recording paper after fixing process is transported to a reverse transporting part for both side image forming. SOLUTION: This device is, capable of severally forming image on either side of a recording paper P by fixing the recording paper P that the image is formed on one side thereof by means of the image forming part by fixing rollers pair, reversing the recording paper P upside down on the inversion transporting part 40, and feeding the recording paper P to the image forming part by the paper re-feeding part. In such a case, the recording paper transporting linear velocity V3 of transporting rollers on the most upstream side for transporting while holding the recording paper P their between on the inversion transporting part 40, is set to the velocity slower than the recording paper transporting velocity V1 of the fixing rollers pair. |
