PROBLEM TO BE SOLVED: To suppress the generation of abrasion or the like on a photoreceptor drum surface due to relative velocity difference at a contacting part between respective photoreceptor drums and a carrying belt. SOLUTION: The photoreceptor drums 1a, 1b, 1c, 1d on which images are formed corresponding to image information and a carrying belt 8 which is used for transportation of the images or transportation of a transfer material and is erected spreadingly by a driving roller 10 or the like are respectively independently driven-controlled by using a plurality of driving vibrating motors DY, DM, DC, DK, Tr and further are driven-controlled so that travel velocities of both surfaces nearly coincide with each other at a contacting part between the respective photoreceptor drums 1a, 1b, 1c, 1d and the carrying belt 8. |
