ELECTROPHOTOGAPHIC METHOD Abstract The invention provides an electrophoto- graphic method of forming a subsequent toner image overlapping one or more toner images previously formed on a surface of an electrophotographic element. The method comprises the steps of: (a) electrically charging the surface and the previously formed toner image or images, (b) forming an electrostatic latent image overlapping the previously formed toner image or images on the surface by imagewise exposing the element, through the previously formed toner image or images, to actinic radiation, and (c) electrographically developing the electrostatic latent image to thereby form the subsequent toner image, and is characterized in that the actinic radiation is of a wavelength outside the range of 400 to 700 nanometers, and in that the density of the previously formed toner image or images to the actinic radiation is less than 0.2.
