Abstract: A self-biasing electrode system for the development of latent electrostatic images provides low background and good solid area image fill by positioning a conductive electrode adjacent to the image surface as the image is being developed by charged making particles. The electrostatic image induces a charge on the electrode whose magnitude is controlled by grounding the electrode through an electrical impedance, for example, either a resistor along or a resistor and capacitor arranged in parallel.
