PROBLEM TO BE SOLVED: To provide a light beam scanner that can perform light exposure based on a correct gradation value.SOLUTION: When a plurality of exposure scanning beams are present along a scanning direction of a light beam scanner, a control unit 15 determines a connection position of the adjacent exposure scanning beams on the basis of exposure scanning data in a beam overlapping allowable area where the edges of the adjacent exposure scanning beams overlap with each other, so as to correct a gradation value of either one of the exposure scanning beam on the first stage of the determined connection position and the exposure scanning beam on the subsequent stage.
