COLOR IMAGE FORMING DEVICE

PURPOSE:To carry out printing and recording with a clear contour by carrying out photoelectric conversion on color image information light emitted from a light emitting means making it into a photoelectron and highly energizing it with a photoelectric conversion multiplying element. CONSTITUTION:The light emitting means 1 which emits light based on the color image information, a photoelectric conversion means 4 which converts this light into the photoelectron, a photoelectronic multiplying means 41 which discharges secondary electrons by the electronic energy of the converted photoelectron and multiplies the secondary electron number, a secondary electron speeding up means which speeds up the multiplied secondary electron, and a fluorescent means 42 which emits light of wave length matching each photosensitive wave length range of a photosensitive recording medium are provided. Then the light of wave length emitted by the fluorescent means 42 is made to irradiate the surface of the photosensitive recording medium. Thus, a high level of brightness can be obtained and maintaining and improving of quality such as the clear printing contour is obtained.
