ABSTRACT:
An optical scanning apparatus includes a laser unit formed by integrating a semiconductor laser and collimator lens, an incident optical system for making a light beam emerging from the laser unit strike an optical deflector while keeping the light beam wider than the width of a deflecting surface of the optical deflector in the main scanning direction, and an imaging optical system for forming the light beam reflected/deflected by the optical deflector into an image on a scanned surface. The laser unit is shifted by a shift adjusting means in a predetermined direction with respect to the optical axis of the incident optical system so as to make an illuminance distribution of scanning lines on the scanned surface become substantially symmetrical about the scanning central axis.
