Color image forming apparatus for forming a plurality of single-color images on a latent image carrier
A color image forming apparatus irradiates a photosensitive drum with exposure light beams to form a plurality of latent images, develops the latent images into visible images, overlies the visible image to form a color image, and transfers the color image to recording paper. In this apparatus, a light reflection surface is formed on the photosensitive drum. Reflected light beams of laser beams from this light reflection surface are detected by a photodetector. The relative positions of the plurality of latent images formed by the laser beams are corrected in accordance with the detection signal from the photodetector. The image registration error of the color image can be accurately corrected without wasting toner or requiring an accurate toner mark detector, and a high-quality color image can be formed at a high speed with a simple arrangement.
