Abstract

PURPOSE: To change a polarization angle so that a primary light may be irradiated to a prescribed position, by detecting the distortion of a correcting laser light, which passes through a light path other than the primary light radiated from an acoustic optical light modulator, from a prescribed position.
CONSTITUTION: Primary light L1 which is caused to include picture signals and is radiated from acoustic optical light modulator 2 is reflected by rotary polyhedral mirror 9 and is irradiated to photo-sensitive drum 10. The distortion of the irraidation position dependent upon the inclination of the rotary polyhedral mirror is corrected by correcting laser light Lr and sensor 12. Laser light Lr irradiates self-scanning image sensor 12 by mirror 9 and passes through it. The distortion of laser light Lr from a prescribed position is converted to an electric quantity on a basis of the output from sensor 12, and the frequency of the carrier is changed by this value to change the polarization angle of primary light L1, and this changed light is irradiated to a prescribed position on photo-sensitive drum 10.
