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.

Abstract: A METHOD OF DEVELOPMENT OF AN ELECTROSTAIC LATENT IMAGE IS GIVEN WHEREIN A CHEMICALLY STABLE, NONAQUEOUS, AMBIPOLAR, LIQUID DEVELOPER COMPRISING AN OLEAGINOUS VEHICLE, SOLID COLORAT PARTICLES, A DISPERSANT SOLUBLE IN THE LIQUID DEVELOPER WHICH IS CAPABLE OF SUBSTANTIALLY SUPPRESSING BACKGROUND DEPOSITS, AND A FIXING AGENT MISCIBLE WITH THE LIQUID WHICH PENETRATES THE COPY PAPER IS EMPLOYED TO DEVELOP AN ELECTROSTATIC LATENT IMAGE BY PRESENTING THE DEVELOPER TO THE IMAGE BEARING SURFACE BY AN APPLICATOR HAVING A SUBSTANTIALLY UNIFORMLY PATTERNED SURFACE OF RAISED PORTIONS AND DEPRESSED PORTIONS WHICH CONTAIN THE DEVELOPER.

Abstract: AN ELECTROSTATOGRAPHIC IMAGING SYSTEM WHEREIN AN ELECTROSTATIC LATENT IMAGE IS DEVELOPED BY PLACING THE IMAGEING SURFACE IN DEVELOPING CONFIGURATION WITH A PATTERNED APPLICATOR SURFACE HAVING A SUBSTANTIALLY UNIFORM DISTRIBUTION OF RAISED PORTIONS OR "LANDS" AND DEPRESSED PORTIONS OR "VALLEYS" AND CONTAINING A RELATIVELY NON-CONDUCTIVE LIQUID DEVELOPER IN THE DEPRESSED PORTIONS THEREOF WHILE THE RAISED PORTIONS ARE SUBSTANTIALLY FREE OF DEVELOPER.
