PROBLEM TO BE SOLVED: To provide a light beam scanner in which the similarity of a plurality of optical paths is enhanced and the stability of the color register is improved. SOLUTION: The light beam scanner 100 is provided with a single deflector 11 in a single casing 10, a plurality of light beams are deflected with the single deflector 11, the optical paths of the plurality of deflected light beams are divided and the plurality of light beams are guided to a plurality of photoreceptors, respectively. In this case, flat mirrors 5A to D arranged on the respective optical paths of the plurality of deflected light beams and cylindrical mirrors 6A to D having refractive power are arranged in the same order, the respective light beams are turned back by the same times, twice or more, on the optical path leading to the plurality of photoreceptors 8A to D, and the corresponding turning back angles of the respective light beams are substantially the same.
