PURPOSE:To enable a satisfactory image to be obtained by providing a constitution where the movement direction of an image receptor receiving an image printed is adjustable. CONSTITUTION:A transfer frame 21 revolves around a pin 23 by rotating a screw 28, and an angle of a direction where the movement direction 10 of an intermediate transfer body belt 9 is adjustable. That is, a right angle formed by the movement direction of the intermediate transfer body belt 9 with a bus at transfer positions of photosensitive drums 5C, 5M, 5Y which are printing positions, is maintained upto a practically adequate value by rotation and adjustment of the screw 28. Then transfer images 17C, 17M, 17Y on the intermediate transfer body of a black line 14 at a copy table are allowed to be double- transferred within a required tolerable value of misregistration, thus obtaining a satisfactory image. |
