PROBLEM TO BE SOLVED: To provide a compact optical scanner that prevents bending of a scanning line and deterioration of wave-front aberration.SOLUTION: Two light sources (2200a, 2200b) are spaced from each other in a z-axis direction. Two light beams emitted from the light sources are made incident on a deflection reflection surface from a direction inclined with respect to a surface orthogonal to a rotation shaft of a polygon mirror 2104A. The two light sources and two couling lenses (2201a, 2201b) are held by a holder 10. The holder 10 is supported by an optical housing 2300A at two places (a receiving part A, a receiving part B) different in position in a direction from the light sources to the corresponding coupling lenses. |
