Abstract
Light reflected from a document surface is given first color dispersion when passing through a prism interface and second color dispersion when passing through another prism interface. The second color dispersion is in an opposite direction to and has larger partial dispersion in a blue range than the first color dispersion. The prism interface may be replaced by an interface of two lenses which interface is a curved surface whose center of curvature is deviated from the optical axis of the reflected light in the auxiliary scanning direction.
