ABSTRACT:
An intermediate transcription drum is supported so as to be driven in contacting relationship with a photosensitive belt. The rotating speed of the photosensitive belt driving motor is controlled by a control unit such that one rotation cycle of the intermediate transcription drum becomes a given cycle. An adjustment of the speed control data for the photosensitive belt driving motor is performed in the interval between electrostatic latent image forming. Thereby, a speed difference between the photosensitive belt and the intermediate transcription drum does not occur, and a plurality of the toner images can be transferred and accurately superposed onto the outer surface of the intermediate transcription drum.
