Abstract: An apparatus for performing a copying operation contains a photosensitive drum, a focusing optical system for directing reflected light from an original image onto the photosensitive drum, a lamp for lighting the original image, a light quantity sensor for detecting the quantity of reflected light from the original image and for controlling the quantity of light of the lamp on the basis of the detected value of the quantity of reflected light, a first filter provided in an optical path of the focusing optical system so as to cut-off light having a wavelength not longer than a predetermined value, and a second filter provided on a light-detection surface of the light quantity sensor. The second filter has a cut-off wavelength point shorter than the first filter.

Abstract: A color image reproduction apparatus capable of producing a polychromatic reproduction of a color original is disclosed. The apparatus includes a light scanner for scanning the color original to be reproduced to thereby form a light image. A prism or a plurality of color filters are arranged for color-separating the light image into red, green and blue light images and a memory is provided for memorizing those color-separated light images. A plurality of marking units are arranged around a transfer drum carrying a copy paper thereon and cyan, magenta and yellow toner images are formed by the respective marking units and toner images are transferred onto the copy paper in substantially perfect registration. The drive timing of each marking unit in response to conveying timing of the copy paper is controlled by a system controller.
