Abstract
Abstract A METHOD IS PROVIDED FOR PRODUCING A PLURALITY OF COPIES OF AN ORIGINAL BY AN ELECTROSTATOGRAPHIC PROCESS REQUIRING ONLY A SINGLE ELECTROSTATIC LATENT IMAGE. AFTER DEVELOPMENT OF THE LATENT IMAGE WITH LIQUID DEVELOPER, THE DEVELOPED IMAGE IS PARTIALLY TRANSFERRED TO A COPY WEB LEAVING BEHIND A RESIDUAL LIQUID FILM IN IMAGE CONFIGURATION. THIS RESIDUAL LIQUID FILM IS THEN REDEVELOPED WITH LIQUID DEVELOPER TO FORM ADDITIONAL COPIES WITHOUT FURTHER NEED OF THE LATENT IMAGE. REDEVELOPMENT CAN BE ACCOMPLISHED AFTER DISCHARGE OF THE LATENT IMAGE TO BELOW THE DEVELOPMENT THRESHOLD.
