PURPOSE:To form an image without color uneveness by varying the conversing quantity of a luminous flux form an original to a color resolving filter in response to a color to be formed into an image and making voltage of a light source to be constant. CONSTITUTION:The light source 3 which moves along a contact glass 2, an original scanning mirror 4, and a converging part 5 which converges the lumi nous flux are provided. Furthermore, the color resolving filter 8 which positions filters of blue, red, green, and black in a light path by a rotating action is provided between a mirror 6 which reflects the luminous flux passing through the converging part 5 and a photosensitive body 7. In the case, the converging amount of the luminous flux which is scanned from the original to the photosen sitive body 7 can be polarized according to the color to be formed into an image, and the energizing voltage of the light source 3 by which the original is illuminated can be made approximately equivalent. Thus, even when the color to be formed into an image differs, since the variation of light quantity against the energizing voltage of the light source 3 is constant, the image with out color uneveness can be formed. |
