ABSTRACT:
An electrophotographic image recording apparatus that forms an electrostatic latent image so that the uniformly charged surface of a photoreceptor is scanned for its exposure with a beam spot of a light beam generated according to image information, to discharge the surface of the photoreceptor up to a medium potential. The electrophotographic image recording apparatus includes a light beam generator capable of varying an amount of light beam and a light intensity distribution pattern of a beam spot on the surface of the photoreceptor, an intensity distribution pattern controller for controlling the light beam generator according to the image information of peripheral pixels, to vary the intensity distribution pattern of the beam spot on the surface of the photoreceptor, and a light beam output controller for controlling the light beam generator to put the exposure energy on pixels, exposed to the beam spots of intensity distribution patterns, at a predetermined value.
