Abstract
A laser scanning device emits a scanning laser beam which scans a predetermined surface to be scanned to form an image consisting of a plurality of pixels on the surface. The laser scanning device determines the intensity of the laser beam for each pixel of an image to be formed, and executes a feed-back control of the laser diode so that the intensity of the laser beam for each pixel accurately corresponds to the gradation level thereof.
