Abstract
An apparatus and a method of controlling a light level of a light beam irradiated by a light source are provided. The light source is caused to irradiate the light beam having a light level determined based on a light level correction value for a specific main scanning position. The light level correction value is calculated based on light level change information indicating the change in the light level correction value for the specific main scanning position changes with respect to an initial light level correction value or a preceding light level correction value.
