Abstract

PURPOSE:To enable uniform exposure of effective near infrared ray, by making common the optical path of image exposing means and that of near infrared ray exposing means, in the vicinity of photosensitive drum surface. CONSTITUTION:The mirror 9' is the dichroic mirror, and on the transparent glass plate, high-and low-refractive index substances are alternately vapor-deposited with multilayer, and the spectral transmittance rate is lower almost over the entire range of visual light and higher from the infrared ray to near infrared ray range. At the back of the mirror 9', As near infrared ray exposure source, a plurality of tungsten lamps 121 are located axially to the drum 1 and it is illuminated with the determined voltage at each color separation and exposure. The light from the lamp 121 exposes the drum 1 with the image exposure of original through the mirror 9'. The near infrared ray transmission filter can commonly be used for the mirror 9' and the near infrared-ray component which can give adverse effect on color separation included in the light image can be rejected with the mirror 9', allowing to increase color separation.
