Abstract

PURPOSE:To prevent the dislocation of an image by making intertransfer distance the multiple of integer of the distance where a belt proceeds in the velocity variation period of the belt corresponding to one rotation of a transfer belt driving roll. CONSTITUTION:The transfer belt 54 is laid among plural rollers including the transfer belt driving roller 55 and plural latent image carriers 53, 53' and 53'' which form developed images obtained by developing electrostatic latent images are disposed on the transfer belt 54. By driving to rotate the transfer belt 54 by means of the transfer belt driving roll 55, the developed images of the respective latent image carriers 53, 53' and 53'' are sequentially transferred on a transfer sheet while carrying the transfer sheet on the belt. Intertransfer distances alpha' and beta' on the transfer belt 54 between the respective latent image carriers 53 and 53', 53' and 53'' are made to the multiple of integer of the distance where the belt proceeds in the velocity variational period of the belt corresponding to one rotation of the transfer belt driving roller 55. Thus, an image forming device in which the mutual dislocation is not easily caused in the image can be obtained.
