Title of the Invention AUTOMATIC DEVELOPMENT ELECTRODE BIAS CONTROL SYSTEM Abstract of the Disclosure An automatic control system for the bias on a development electrode in which a plurality of ground- insulated, narrow floating electrodes are spaced along a line adjacent the entrance of a liquid developer applicator unit. The floating electrodes relatively scan image areas of the surface of an organic photoconductor carried by a conductive support moving through the developer unit. Owing to conduction of a charge from the photoconductive surface through the developer liquid to the floating electrodes, they assume potentials each of which is a function of the average potential of the image area subtended by the floating electrode. The potential of each floating electrode is sensed by a high input impedance measuring circuit which selects the potential of the low- est value, amplifies the selected potential and applies the amplified voltage to the biasing electrode or electrodes of the developer system. A fully charged and unexposed area of the surface following the image area produces a reverse bias which cleans the biasing electrodes as the fully charged area passes through the developer system.
