Abstract

PURPOSE:To perform other discoloring and color conversion as well as erasing of black part by using a single layer photoreceptor, by respectively forming a nonmagnetic toner image in correspondence with the black part of an original image and that in correspondence with the colored part of an original image. CONSTITUTION:After a photosensitive drum 1 is uniformly charged with a charger 2, the exposure of image is made by an exposure 3. Electrostatic latent image of the part corresponding to the black part is formed by using a red filter as a color decomposition filter 4. Uniform charge is made by a charger 2 while keeping a black magnetic toner on the photoreceptor drum 1 to form electrostatic latent image corresponding to the black and red parts by using a cyan filter afterwards. Development is made by a development device 6 accommodating a nonmagnetic toner to obtain the nonmagnetic substance layer toner image corresponding to the colored part of the original. Thus, the black part is erased by using a single-layer photoreceptor and color decoloring and conversion can be made also.
