IMAGE FORMING APPARATUS AND EXPOSURE POSITION ADJUSTING METHOD

摘要

According to an image forming apparatus and an exposure position adjusting method of one aspect of the present invention, an exposure section scans a plurality of light beams to form a plurality of electrostatic latent images periodically along a main-scanning direction of the photoreceptor at a predetermined pitch in a sub-scanning direction of the photoreceptor. Next, a surface potential detecting section detects electric potentials of the plurality of electrostatic latent images formed on the surface of the photoreceptor, along the main-scanning direction. Furthermore, a controller calculates exposure timings by the plurality of light beams in the exposure section on the basis of a detection result by the surface potential detecting section.
