Abstract

PURPOSE:To obtain a specified color sensitivity, by displacing in a luminous flux the terminal position of spectral distribution correcting means for setting color sensitivity of a copying apparatus to a specified color to adjust exposure. CONSTITUTION:An optical projection system for projecting the optical image of the original to be copied placed on original platen 8 on photoreceptor 2 is provided with filter 13 for correcting spectral distribution with its terminal located in effective optical flux L, and an exposure controller for displacing the terminal in flux L by moving filter 13, in the copying apparatus provided with slit 12 for regulating the exposure area of the optical image on photoreceptor 2. The exposure controller composed of controller 18 and servomotor 17 controls exposure by moving base plate 14 for supporting filter 13 in the direction A or B.
