Abstract
In a color-image copying apparatus, a light source emits light to shine upon an original. An optical system utilizes the light with which the original is illuminated, for copying color image information on the original, onto a recording medium. The light source includes an electron gun emitting an electron beam, a controller for controlling intensity of the electron beam emitted by the electron gun, a deflector for deflecting the electron beam emitted by the electron gun, and a fluorescent portion irradiated with the electron beam deflected by the deflector, for emitting a plurality of fluorescence-luminescing colors.
