Abstract
PURPOSE: To prevent uneven transfer and disturbances of transfer images owing to seam parts by specifying the overall length of a dielectric belt and synchronizing its movement to the movement of a photoreceptor.
CONSTITUTION: A dielectric belt 15 which is to be disposed in adjacency to one side of a photosensitive drum 2 is formed in the closed loop form comprising superposing and sewing both end parts of a flexible dielectric belt with a specified margin for joining and its overall length is defined at integer times the length S of one segment of the photosensitive drum 2. In addition, it is turned in synchronization to the same speed as the peripheral speed of the photosensitive drum 2 so that its seam part 16 always aligns to the non-image forming region U of the photosensitive drum 2. Then, at the time when the transfer sheet having been attracted and held to the dielectric belt 15 is detached from the dielectric belt 15 by a destaticizing device 27 and is sent to the next step after having been transfered with the toner images of the first or second photoconductive thin plate 7 or 12 by a staticizing device 26, the transfer to the seam part 16 is prevented and the intended object achieved.
