ABSTRACT:
An image forming apparatus which repeats image create/transfer processing while rotating a photosensitive member and a transfer medium in a sub scanning direction and thereafter transferring the toner image onto the transfer medium, for a plurality of toner colors which are different from each other, to thereby lay toner images in respective toner colors over each other on the transfer medium and accordingly form a color image. The apparatus corrects transfer start positions of toner image in at least one or more toner colors out of the plurality of toner colors based on a registration control amount which is necessary to correct relative registration deviations among toner images on the transfer medium.
