摘要： A laser beam scanning system includes a laser for emitting a laser beam modulated with image information to be recorded and a deflecting device, such as polygon mirror, for deflecting the laser beam over a predetermined angle repetitively, so that the laser beam is scanned on a scanning surface, thereby an image is formed on the scanning surface. When a plurality of laser beams are used at the same time, the plurality of laser beams are arranged in an array inclined with respect to the scanning direction. In this case, a sync sensor generates a sync signal in response to a laser beam received in the first place. When a polygon mirror is so structured to have a reflecting surface which is defined by a curved surface having a predetermined radius of curvature, a f.theta. lens may be discarded. In this case, when a transparent layer is formed on this curved reflecting surface, no distortion in scanning speed is produced even without using any electrical correction. Besides, it is also preferable to control the intensity of laser beam so as to maintain the image density of a resultant image at constant.
