Abstract
An image forming apparatus that is capable of simplifying controls for light sources. A polygon mirror with four reflective surfaces deflects light beams emitted from first and second light sources. A housing in which the light sources and the polygon mirror are arranged is configured so that optical paths of the light beams toward the polygon mirror are parallel to a virtual plane containing a rotating axis of the polygon mirror, and so that the light beams are incident on adjoining reflective surfaces of the polygon mirror. First and second driver ICs drive the first and second light sources in one of operation modes. A control unit outputs the same operation mode signal to the first and second driver ICs at the same timing so that the first and second light sources operate in the same operation mode.
