PURPOSE:To execute smoothly double face copying during the work by giving bend to the reverse side on the way of a course between the position, just after a copy paper passed through a fixing device is inverted and is carried while bending, and a circulating belt. CONSTITUTION:After fixing, the copy paper is brought into contact with a carrying direction switching plate 27 through feeding rolls 26 and 26' and is inverted and is led into a curl straightening device 29 while bending along a path of a surface of second degree downward in the vertical direction. When a driving roll 44 of the curl straightening device 29 is rotated, a curl straightening belt 45 is moved, and pressing rolls 42 and 43 are ratated, and the curled copy paper is led between a curl straightening roll 41 and the curl straightening belt 45 and is moved on the circumferential face of the curl straightening roll 41 and is pressed to the curl straightening belt 45 and is bent in the side opposite to the bend side in the path of the surface of second degree. As the result, curl is straightened, and the copy paper is so inverted that an image is transferred to the other face. |
