Abstract
In an image forming apparatus that executes exposure for discharging a photoconductive drum by a light emitting unit by which an electrostatic latent image is formed, a duty ratio of a drive signal for a driving unit that exposes the photoconductive drum for performing discharging of the photoconductive drum is set to be 100%, and it is thereby possible to suppress generation of radiation noise resulting from the drive signal for the discharging.
