ABSTRACT:
A color-image forming apparatus includes: an electrostatic latent image holder; electrostatic latent image forming unit for forming a plurality of electrostatic latent images on the image holder; a scanning unit for scanning the electrostatic latent image holder periodically at predetermined timings; developing devices for developing each of the plurality of electrostatic latent images by toners of each of different colors respectively, and forming thus developed toner image on the image holder; a simultaneously transferring device for simultaneously transferring the plurality of toner images onto a transfer medium; fixing device for fixing the toner image on the transfer medium; and timing-setting unit for setting a timing at which said scanning means starts scanning at each of slow scanning pitches in the direction of fast scanning for each of the plurality of colors; wherein the timings which are allotted to each of the colors are different each other so that the starting position of the scanning of each color at each of slow scanning pitches in the direction of the fast scanning is successively shifted at a predetermined distance.
