Abstract:
1. A color image forming apparatus, comprising: a photoreceptor having an image carrying surface; a first exposing device, which exposes the image carrying surface to form a first latent image; a first developing device, which develops the first latent image to form a first toner image on the image carrying surface; a second exposing device, which exposes the image carrying surface to form a second latent image; and a second developing device, which develops the second latent image to form a second toner image on the image carrying surface, wherein the first exposing device comprises, a light source, which emits a light beam, a deflector, which deflects the light beam on the image carrying surface for making a scanning line, a first optical system, which is provided between the deflector and the image carrying surface, and focuses the light beam on the image carrying surface, and a first adjustor, which adjusts an alignment between the first optical system and the image carrying surface for correcting variation of lateral magnification in a primary scanning direction of the optical system so that the first toner image and the second toner image are superposed on a recording sheet.
