Abstract
A rectangular array of rod lenses is arranged between an original document and a photoconductive member, and the document and photoconductive member move relative to the rod lens array at the same speed. The document is illuminated for three sequential color separation exposures so that three color images are formed on the surface of the photoconductive member by the rod lens array. Due to the construction of the means for illuminating the document, the brightness of the illumination is different for the three color separation exposures. This is compensated for by varying the number of rod lenses for the three color separation exposures and thereby the cross sectional area of the rod lens array which constitutes an exposure aperture so that the effective brightness of illumination is the same for the three color separation exposures.
