OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS |
摘要 |
An optical scanning device includes a light source, a deflector, and an image-forming optical system. The deflector includes a deflecting surface for deflecting light beams in a main scanning direction. The image-forming optical system includes two relay lenses having a positive power in the main scanning direction. The relay lenses cause main light beams of light beams emitted from the light source to cross near the deflecting surface in the main scanning direction.
