<p><P>PROBLEM TO BE SOLVED: To conduct favorable double-sided print with restricted paper jam by correcting curl in paper without enlarging space downstream of a fixing part in an image forming device. <P>SOLUTION: A first carrying direction changing part 40 of a branch part 30 distributes paper P to a first paper carrying passage 60 and a second paper carrying passage 70. The second paper carrying passage 70 goes to a double-sided print carrying passage 80. For double-sided print, paper P is once sent to the first paper carrying passage 60, and the carrying direction is changed, so that it is sent through the second paper carrying passage 70 and the double-sided print carrying passage 80 to a transfer part 9. The first paper carrying passage 60 is provided with a curvature part 61 having a radius of curvature R1, and the second paper carrying passage 70 is provided with a curvature part 71 having a radius of curvature R2. The radius of curvature R2 of the curvature part 71 in the second paper carrying passage 70 is smaller than the radius of curvature 61 of the first paper carrying passage 60. Downstream of the curvature part 71, a curl correcting means 72 is disposed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
