ABSTRACT:
A liquid toner based imaging machine includes a movable photoconductive member carrying an electrostatic latent image. A developing station contains a source of toner liquid that includes charged toner particles. The station is operatively associated with the carrier for contacting the carrier with the liquid for which develops the latent image by effecting the transfer of toner particles to the image. The developing station includes a developer electrode charged to a voltage intermediate voltages on the carrier representative of background and information of the image for attracting toner particles to an elemental area of the carrier when the electric field between the carrier and the electrode is directed towards the elemental area. The deposition of toner particles on the surface of the electrode is inhibited during development of the image by coating the surface of the electrode facing the carrier with a polymer material having a conductivity increasing additive.
