Claims

[Claims for Utility Model Registration] Spectral exposure of an original image on a photoreceptor using red, green, and blue color separation filters, so that the color image charge latent image of each color has a complementary color relationship with the color of the color separation filter. In a color electrophotographic device that forms a color image by sequentially repeating the process of developing with three color toners, cyan, magenta, and yellow, using three color separation filters, -, the color toner images are superimposed, and a reversed image of the original image is formed. a transparent photoreceptor for masking to be formed;
Image exposure through a mask plate created on this transparent photoreceptor,
1. A color electrophotographic apparatus comprising means for performing image exposure on a photoreceptor before or after image exposure.
