Abstract
PURPOSE: To enable formation of a copied image optimally discernible in accordance with constituent colors of an original, by regulating spectral distribution characteristics of an original illumination light source and correcting light quantity change due to this.
CONSTITUTION: Spectral distribution characteristics of original illumination halogen lamp 2 are regulated by controlling lighting voltage of lamp 2 and width of slit 9 opposite to photoreceptor 7. Light quantity change due to this regulation is corrected by slit 8, and exposure quantity of photoreceptor 7 is kept always constant even after regulation for color reproduction, thus permitting formation of a copy optimally discernible in accordance with originals of various colors by regulating color reproductivity and reproduction density in accordance with the desirable colors of the original.
