Abstract:
    In a beam scanning apparatus of an electrophotographic color printer, at least two beam deflectors, each having a deflection disk consisting of at least two sectors and a driving source for rotating the deflection disk, deflect and scan an incident beam. The deflection disk has a pattern formed thereon for diffracting and scanning the incident beam. A plurality of light sources, arranged between the beam deflector and a photoreceptor, emit light to the deflection disk. A beam path changing unit changes a proceeding path of the beam deflected by the respective beam deflectors to proceed toward the photoreceptor. A beam correcting unit, arranged between the respective beam deflectors and the photoreceptor, corrects the input beam having its path changed by the beam path changing unit.
