Abstract
The invention provides electrophotographic apparatus for forming a subsequent toner image overlapping one or more toner images previously formed on a surface of an electrophotographic element. The apparatus includes means for electrically charging the surface and the previously formed toner image or images, and means for 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. The latent image forming means provides actinic radiation of a wavelength outside the range of 400 to 700 nanometers with the density of the previously formed toner image or images to the actinic radiation being less than about 0.2. The apparatus further includes means for electrographically developing the electrostatic latent image to thereby form the subsequent toner image.
