Method of electrophotographic wet reversal development

Abstract

This invention relates to a method for electrophotographic wet reversal development comprising charging an electrophotographic photoreceptor comprising a substrate and a photosensitive layer coated thereon, exposing the electrophotographic photoreceptor to form an electrostatic latent image on the surface of the photosensitive layer, and developing the electrostatic latent image by carrying the electrophotographic photoreceptor through a wet reversal developing device having a developing electrode in substantially a linear form having a projected width of 30 mm or less and applying a bias voltage to said developing electrode. Usually, the bias voltage applied is 80% or more of the surface potential of the photoreceptor and the development is carried out by passing the photoreceptor at a rate of 0.5-20 m/min through the developing device. This method produces images with less edge effect and excellent tone reproduction. The developing electrode is simplified resulting in improved maintainability.
