Abstract: Disclosed is a color electrophotographic method according to which color images of high quality can be stably obtained by digital signal processing of image information. This method comprises converting a read image signal to a digital signal, subjecting the digital signal to signal processing which includes tone correction of photoreceptor and tone correction of toner color density, exposing charged photoreceptor with a light having intensity modulated according to the signal to form a electrostatic latent image and then developing the latent image.
