ABSTRACT:
There is described an image-forming apparatus, which can prevent unevenness of an image by controlling the brightness of light-sources. The apparatus includes a light source, including a plurality of light-emitting elements aligned within a predetermined width; an exposure-controlling section to individually control each of intensities of light beams emitted by the plurality of light-emitting elements; and a memory section to store light-intensity compensation data for each of the plurality of light-emitting elements. The image is formed by simultaneously exposing the light beams aligned within the predetermined width onto the photosensitive recording medium, and the exposure-controlling section controls each of the plurality of light-emitting elements based on the light-intensity compensation data concerned, so that each of intensities of the light beams substantially coincides with each of target intensities set in advance.
