When an image is scanned and recorded on a photosensitive material, the quantity of emitted light of each of light emitting elements is corrected by controlling, based on digital image data, quantities of light beams emitted from light emitting portions of three colors, which each consist of a plurality of light emitting elements. A drive signal level of each of the light emitting elements is corrected for the same digital image data so that the light emitting elements which emit light beams of the same color have the same quantities of emitted light. Subsequently, the drive signal level of each of the light emitting elements is corrected for predetermined digital image data so that the ratio of the quantity of emitted light between the light emitting elements, which emit light beams of different colors, is set at a predetermined value.
