Abstract
An image forming apparatus including a photoreceptor having an image carrying surface, first and second exposing devices to expose the image carrying surface to form first and second latent images, and first and second developing devices to develop the first and second latent images to form first and second toner images on the image carrying surface. The first exposing device has a light source which emits a light beam, a deflector which deflects the light beam on the image carrying surface to form a scanning line, a first optical system to focus the light beam, 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 the primary scanning direction of the optical system so that the first toner image and the second toner image are superposed on a recording sheet.
