Abstract
An image forming apparatus includes an exposure unit, including a plurality of light-emitting units that correspond to a respective plurality of pixels and a lens array optical system, for emitting exposure light. A photosensitive member is exposed by the exposure light from the exposure unit. A correcting unit estimates, from image data, an intensity of ghost light at a position of each pixel on the photosensitive member in a case when the photosensitive member is exposed by the exposure unit, using the image data, and corrects the image data based on the estimated intensity of the ghost light.
