ABSTRACT:
An image recording apparatus comprises a beam generating unit for generating a light beam modulated in accordance with input image signal, a beam deflecting unit for scanning a recording medium using the light beam generated by the beam generating unit, the beam deflecting unit comprising a rotating polygon mirror having a plurality of reflecting surfaces. The apparatus can be operated in a mode for forming an image using all the reflecting surfaces of the rotating polygon mirror and in a mode for forming an image using predetermined reflecting surfaces of a plurality of reflecting surfaces of the rotating polygon mirror. The apparatus thus permits the dot density to be changed to a plurality of values with a simple structure so that image information can be recorded with high definition on the surface of a recording medium.
