Abstract

PURPOSE:To obtain a composite picture by providing a transfer drum in parallel to a photoreceptor drum, and by further providing a driving means of driving the transfer drum at the same speed with and in the opposite direction to the photoreceptor drum and a means of moving the transfer drum in its axis direction. CONSTITUTION:Transfer drum 17 is provided in parallel to photoreceptor drum 1 and also provided with copy paper clipper 18. Copy paper P in cassette 19 is fed by roller 20 and gripped by gripper 18. Transfer drum 17 is driven by motor 38 independently of photoreceptor drum 1 to rotate at the same peripheral speed with and in the opposite direction to drum 1. Then, the latent image position on the photoreceptor drum is synchronized with copy paper P. In this constitution, one cycle up to the completion of the transfer process of the 1st original is finished the first and the process of transferring the original image of the 2nd original on same copy paper is repeated to perform multiple transfer.
