Abstract

PURPOSE: To obtain a color image of good reproducibility free from any color fog by removing the light of at least the infrared part out of the light outside of the visible region in exposure luminous flux then performing exposure by the use of color separating filters.
CONSTITUTION: A color original 0 is slit-scanned by a lamp 2 and a mirror 3, and the light reflected by a mirror 4 is removed of the light of at least the infrared part other than the visible region by an in-line mirror 5, thereafter it is reflected from a mirror 6 and is color-separated by using the blue filter FB, green filter FG and red filter FR mounted to a rotating shaft 9. This light is exposed to a photosensitive drum 11 through mirrors 7, 8, and is copied superposedly on the same recording sheet S at every color, whereby the color image is obtained. This enables the color image of good reproducibility free from any color fog to be obtained even if a photoconductor having sensitivity to infrared light is used for the photosensitive drum 11 and even if the filters FB, FG, FR which allow the transmission of some infrared rays are used. It is equally well to use a through-lens that removes the light of the infrared part.
