ABSTRACT:
An optical scanning apparatus controls an output of a light source for forming an electrostatic latent image on an image carrier. The optical scanning apparatus includes a correction amount control unit configured to variably control a light quantity correction amount of the light source according to a scanning position on the image carrier during one scanning operation with a beam generated from the light source, an output signal level changing unit configured to change a level of an output signal from the correction amount control unit, and a light quantity control unit configured to control a light quantity of the light source according to the scanning position based on a signal from the output signal level changing unit.
