Abstract
A scanning optical device has a light source, a deflector for deflecting light emitted from the light source, and an optical system for guiding the light emitted from the light source onto a surface to be scanned. The scanning optical device incorporates a mechanism for displacing a refraction section or/and a diffraction section of the optical system.A color image forming apparatus incorporates the scanning optical devices and image carrying members corresponding thereto.
