Abstract
An image forming apparatus capable of suppressing density unevenness of a toner image formed on a photosensitive member. A light amount of a light beam that exposes an end portion of the photosensitive member is made different from a light amount of a light beam that exposes a central portion thereof in order to suppress a density difference between a toner image density at the central portion of the photosensitive member and that at the end portion thereof in a scanning direction of the light beams.
