ABSTRACT:
The present invention relates to an optical scanning system for deflecting a light beam from a light source by a rotating deflector, reflecting the deflected light beam onto an f.theta. mirror having f.theta. characteristics, and focussing the reflected light beam as a light spot on a scanned surface to thereby carry out optical writing and optical scanning. The f.theta. mirror is unitedly formed with an optical housing.
