ABSTRACT:
A copying machine capable of color copying includes a filter apparatus for color-separating scanning light for scanning original images, and the original images are copied by electrophotographic process. The filter apparatus includes mirror filters having color separation filters of blue, green and red, respectively deposited on mirror surfaces and a half mirror, and these mirrors are arranged apart from each other at an angle of 90.degree., so that the apparatus as a whole has a cylindrical shape. The light scanned the original images is reflected by the filter mirrors, and latent electrostatic images corresponding to respective colors are formed on a photoreceptor drum.
