Abstract
There is provided an image forming apparatus that reduces an operation speed of a unit configured to generate pieces of correction data with which the light intensity of laser light is corrected. Pieces of first correction data in a scanning direction of a photoconductor drum are associated with light sources and stored in memories. For a plurality of regions of the surface of the photoconductor drum, a CPU outputs, for each of the regions, pieces of correction data including pieces of second correction data for correction of electric potential characteristics of the region. The positions of pieces of first correction data match some of the positions of pieces of second correction data. A laser driver IC controls light intensity of laser light at the timing of the pieces of second correction data in accordance with a piece of first correction data and a piece of second correction data.
