Abstract
A color separation system for use in a color copying apparatus including blue, green and red reflection filters as well as blue and green transmission filters. The blue and green transmission filters are disposed in front of the blue and green reflection filters, respectively, so that light passes through the transmission filters twice. The color copying apparatus includes a photosensitive member which is exposed with light passing through the color separation system, an image sensor for reading an image of an color original, and a light adjusting filter for adjusting a quantity of light impinging on said image sensor. The three reflection filters and the light adjusting filter are mounted on a rotary member. One of these filters is selectively positionable in an optical path according to the rotated position of the rotary member.
