Abstract
An image forming apparatus includes a laser light source configured to emit a light beam, a photoconductor drum configured to be driven for rotation on which a latent image is formed by the light beam, a rotatable polygonal mirror configured to rotate about a rotation axis and have a plurality of mirror planes which deflect the light beam so that the light beam scans the photoconductor drum, and a CPU configured to perform a dither process on input image data and correct image data which has been subjected to the dither process using correction amounts based on inclinations of the plurality of mirror planes relative to the rotation axis of the rotatable polygonal mirror.
