ABSTRACT:
An optical scanning device includes a deflecting unit that deflects a laser beam from a light source in a main-scanning direction; a scanning imaging unit that focuses the laser beam deflected by the deflecting unit on a scanning surface and scans the scanning surface with focused laser beam; and a light receiving unit that detects optical intensity of the laser beam and a synchronous timing in the main-scanning direction and that includes a plurality of photodetecting elements arranged on a substrate in the main-scanning direction.
