摘要： An electrophotographic developing method for compensating an unwanted spectroabsorption in coloring agent wherein an electrostatic latent image in a color spectrum, and a second electrostatic latent image in another color spectrum corresponding to the unwanted absorption of the first electrostatic latent image are in opposition with a narrow gap in between. A coloring agent corresponding to the first latent image is fed into the gap and the amount of color agent selectively attached to the first electrostatic latent image is controlled by the second electrostatic latent image.

摘要： An electrophotographic reversal developing process where a charged electrophotographic element exposed to an optically negative image on an image bearing member where the area of the negative image is not over 10 percent of the area of the image bearing member. The electrophotographic element is next disposed with respect to a developing electrode which is completely electrically insulated from its surroundings to thereby induce on said electrode a potential which causes an electric field to occur at the image portions of the whole electrostatic latent image which is oppositely directed from that occurring at the background portion which corresponds to the area of maximum charge density. Next, toner particles having a charge of the same polarity as that of the background portion are introduced between the developing electrode and the electrophotographic element to develop the image portions.

摘要： An electrophotographic device for reproducing a colored original characterized by the interconnection of a plurality of processing units each having a corona charging means, a color-decomposing filter of a color corresponding to a unique color constituent of the colored original, and a developing means for applying a toner of a color complementary to the color of the filter, the elements of each developing unit being arranged in the sequence mentioned above. The interconnected processing units are moved across the surface of a stationary electrophotographic sensitive material on which the image of the colored original is projected, the original also being held in a stationary position whereby the colored original is reproduced on the surface of the sensitive material after all processing units are moved thereacross.
