Claim:
1. An image forming apparatus comprising: a photosensitive member; a scanning unit configured to perform scanning over the photosensitive member with a laser beam that is irradiated from a light source; a width correction unit configured to correct exposure time for individual latent images respectively corresponding to pixels of image data such that widths of the latent images in a moving direction of a spot of the laser beam become closer to a constant width; a luminance correction unit configured to correct luminance of the laser beam for forming latent images such that an exposure amount per unit time is greater for a second position than for a first position among exposure positions on the photosensitive member, the first position being scanned at a first scanning speed, and the second position being scanned at a second scanning speed that is higher than the first scanning speed; and a density correction unit configured to correct a density value of each of the pixels of the image data according to a scanning position of the laser beam on a surface of the photosensitive member.
