SCANNING OPTICAL DEVICE AND IMAGE FORMING APPARATUS |
| 摘要 |
A scanning optical device includes a deflector deflecting a light beam emitted from a light source, and a pair of optical component groups arranged on both sides of the deflector in a sub-scanning direction and focusing the light beams deflected by the deflector to form images on a surface of an image carrier. Each of the optical component groups has a lens focusing the light beam deflected by the deflector in the sub-scanning direction, and a mirror reflecting the light beam passed through the lens toward the surface of the image carrier. One lens of one optical component group and the other lens of the other optical component group are supported so as to deform in the opposite directions each other in the sub-scanning direction when they are thermally deformed. |

1. A scanning optical device comprising:
a deflector deflecting a light beam emitted from a light source, and a pair of optical component groups arranged on both sides of the deflector in a sub-scanning direction and focusing the light beams deflected by the deflector to form images on a surface of an image carrier, wherein each of the optical component groups includes
a lens focusing the light beam deflected by the deflector in the sub-scanning direction, anda mirror reflecting the light beam passed through the lens toward the surface of the image carrier,one lens of one optical component group and the other lens of the other optical component group are supported so as to deform in the opposite directions each other in the sub-scanning direction when they are thermally deformed. |
