| 摘要 |
In an optical scanning apparatus, the shape of a sub-scanning section of a transmissive imaging optical element on which a light beam subjected to scanning and deflected by a deflecting surface of an optical deflector is incident twice, the tilt angle of a reflective optical element disposed in an optical path between the optical deflector and a surface to be scanned, and the relationship between the transmissive imaging optical element and the reflective optical element are provided. |
