PROBLEM TO BE SOLVED: To provide a double-face image forming device capable of increasing printing speed in double-face continuous printing, reducing deterioration of the printing speed in double-face continuous printing on paper sheets varied in paper size, and carrying out stable printing with a skew or a jam of paper prevented even in double-face continuous printing on paper sheets greatly varied in paper width. SOLUTION: This double-face image forming device is provided with a reversing roller 17 conveying paper by means of a paper reversing mechanism, a paper re-feeding roller 21 conveying the paper for joining it from a paper re- feeding mechanism to an image forming part, a D cut roller 18 conveying the paper from the paper reversing mechanism to the paper re-feeding mechanism via a transverse resist movable plate 22, and a double-face conveying roller 19, and the reversing roller 17, the D cut roller 18, the double-face conveying roller 19, and the paper re-feeding roller 21 are driven for conveyance independently of each other. |
