A Review of Architectures and Process Configurations for Electrophotography

Paper presented at a symposium on Electrophotography organized by the Science Committee of The Royal Photographic Society on 12-17 September 1976 in Cambridge.

Abstract

This review of present day electrophotographic technology deals primarily with the reproduction of documents. Pictorial electrophotography and xeroradiography using basically similar technology are much less advanced.

The choice of proven photoconductors employed in electrophotography is restricted to a limited number, used in a variety of structures including evaporated, coated and laminated layers on sheets, drums and belts. The interdependence of the photo-conductor type and the configuration of the imaging procedure can be proven in typical examples. An attempt at classification of technologies will however rather be based on the process than on the photoconductor. Specific configurations of each class will be discussed.

An outlook on future developments in technology based on known possibilities and limits of electrophotography is given.
