Abstract

Development of electrostatic charge patterns (e.g., electrostatic latent images) carried on a support is accomplished in an electrographic process in which during development, an electrical field which is greater than the electrical breakdown value of the developer (i.e., greater than the maximum electrical field that the developer can support without undergoing electrical breakdown) is established across the developer in the development area. The process enables development of high quality, large solid-area images at high processing rates.
