PROBLEM TO BE SOLVED: To comprise an exposure device that is capable of forming a high-quality image even if a photographic paper feeding speed is varied. SOLUTION: Two laser light sources 13R-T, 13R-D and two modulators 14R-T, 14R-D are provided to send two laser beams LB, LB. These two laser beams LB, LB are reflected by inclined mirror surfaces 16MT, 16MD of a polygon mirror 16, the laser beams LB, LB are guided so as to get closer to each other, and exposure is performed while irradiating a photosensitive surface of photographic paper P in a positional relationship that the laser beams LB, LB are adjacent to each other in a sub-scanning direction.
