Abstract: PURPOSE:To always obtain an image data with a prescribed density by controlling a light emission quantity command means so as to attain a prescribed light receiving quantity and deciding the light emission quantity based on the result of comparison by a light receiving quantity comparison means. CONSTITUTION:At least part of a light radiating from a light emission means 1 is received by a photodetector means 3 and an output of the photodetector means 3 is compared with a reference comparison value with a photodetector quantity comparison means 2.
