Claim:
1. An image forming apparatus comprising: a latent image bearer; a latent image forming unit that includes a light source that emits light with intensity corresponding to image data, and forms a latent image on the latent image bearer with the light from the light source; a correction data generating unit that generates correction data of an intensity of the light source for each position on the latent image bearer; and a correcting unit that corrects the intensity of the light source by a correction amount based on the correction data when the latent image forming unit forms a latent image, wherein the correction data generating unit includes: wherein the excessive correction suppressing unit outputs the correction data after making the amount of change from the immediately preceding latent image formation position zero, with respect to the position at which the absolute value of the restored value exceeds the absolute value of the correction value.
