PURPOSE:To record a polychromatic image having no color deviation at a high speed through single-time image exposure by providing a photosensitive layer on a conductive member and laminating and arranging an insulating layer which contains plural kinds of different-color filter on the surface of the photoconductive layer. CONSTITUTION:The photoconductive layer 2 is provided on the conductive member 1 and the insulating layer 3 containing numbers of necessary color separation filters, e.g. filters of red (R), green (G), and blue (B) is laminated and arranged on the photoconductive layer 2 to form the photosensitive body of polychromatic image formation. The photosensitive drum composed of this photosensitive body is rotated as shown by an arrow (a) and the entire surface is charged electrostatically by a charging electrode 4. Then, discharge is carried out from an electrode 5 having an exposure slit to perform image exposure. The entire surface is exposed by light sources 6B, 6G, and 6R after the exposure to form latent images of respective color parts of the color separation filters FB, FG, and FR, and those images are developed repeatedly with toner particles of corresponding colors to obtain a polychromatic image. Thus, the polychromatic image having no color deviation is recorded at a high speed through single-time image exposure. |
