Abstract
An image forming apparatus includes a signal generation unit configured to generate a light-emission signal. The signal generation unit stores information relating to a toner non-adherent area oriented light-emission pattern having been set beforehand. The toner non-adherent area oriented light-emission pattern is a light-emission pattern that causes a light irradiation unit to emit light in such a way as to prevent toner particles from adhering to a photosensitive member. When the light irradiation unit scans respective portions corresponding to two pixels adjacently disposed in a scanning direction a based on a part of the light-emission signal generated based on the toner non-adherent area oriented light-emission pattern, at least one of (a) light-emission start timing of light irradiation unit and (b) light-emission termination timing of the light irradiation unit is differentiated between the two pixels.
