Abstract
A modulated laser beam emitted from a semiconductor laser is deflected by a rotating light beam deflector to scan a desired surface. The frequency of an image scanning clock signal and the intensity of the laser beam from the semiconductor laser are varied according to a scanning rate at which the surface is scanned by the modulated laser beam.
