PROBLEM TO BE SOLVED: To provide an optical scanner where scanning light from a reflection mirror is easily adjusted in a subscanning direction. SOLUTION: A raster type optical scanner 2 guiding at least one scanning light beam 43 to a photoreceptor 13 is equipped with the reflection mirror 11 making the scanning light beam 43 incident on the photoreceptor 13 and a stay member 15 to which the mirror 11 is attached. The member 15 can turn or move, and the scanning light beam 43 scanning the photoreceptor 13 is moved in the subscanning direction by turning or moving the member 15. |
