Abstract
An image forming apparatus comprises a rotationally driven photosensitive body, a charging device that charges a surface of the photosensitive body, an exposure light source that forms an electrostatic latent image by exposing the surface of the photosensitive body to light, a developing device that forms a toner image by developing the electrostatic latent image using toner, a transfer member that transfers the toner image to a sheet, a first memory that stores a cumulative image formation amount for each one of N exposure regions, and a control circuit that controls the exposure light source.
