A color image forming apparatus includes a light source, a light deflector for deflecting a light beam emitted by the light source, an image carrier, an optical system for guiding the light beam emitted by the light source onto a surface of the image carrier, and a plurality of scanning optical devices each having the light source, deflector and optical system. A distance from a rotation axis of the deflector to the image carrier is smaller than a length of an effective scanning range on the image carrier. An incidence angle of the light beam which becomes incident on the image carrier in a main scanning plane is not more than 27 DEG in the entire effective scanning range. <IMAGE> |
