ABSTRACT:
A light beam is modulated in accordance with an image signal, which is made up of a series of image signal components representing an image recorded on a recording medium, and the modulated light beam is caused by a light beam scanning system, which includes a rotating polygon mirror, to two-dimensionally scan a recording material, the image being thereby reproduced on the recording material. The light beam modulated in accordance with image signal components of the image signal, which correspond to positions lying along each scanning line on the recording medium, is utilized to scan along a plurality of scanning lines on the recording material such that parts of adjacent scanning lines on the recording material may overlap one upon the other. The intensity of the light beam is changed each time the light beam scans along one of the plurality of the scanning lines on the recording material. Each scanning line composed of the plurality of the scanning lines on the recording material is thereby prevented from having an appearance which is not sharp and the sharpness of the image reproduced on the recording material is kept high.
