Abstract: THE SUBJECT MATTER OF THIS PATENT APPLICATION IS DIRECTED TO A NOVEL PROCESS OF IMAGE DEVELOPMENT UTILIZING CONVENTIONAL LIQUID DEVELOPERS. IT HAS BEEN DETERMINED THAT DUE TO THE STRATEGIC PLACEMENT OF A CORONODE BENEATH THE SURFACE OF A LIQUID DEVELOPER THE DEVELOPMENT ZONE MAY BE LOCALIZED AND DEVELOPMENT ACTION CONTROLLED EXTERNAL-

LY BY SELECTIVELY DEFORMING THE LIQUID DEVELOPER THUS RESTRICTING CONTACT OF SAID DEVELOPER TO THE PARTICULAR IMAGE AREAS TO BE DEVELOPED.

Abstract: A transducer applying the Johnsen-Rahbek effect wherein the frictional force between two electrodes separated by electrostatically chargeable material is augmented by an increase in potential applied to the electrodes. The transducer measures or reads out the potential or charge patterns on the electrostatically chargeable material which may be a semiconductor, dielectric or other charge carrying surface and converts the force variations into electrical signals.

Abstract: A PHOTOELECTROPHORETIC IMAGING SYSTEM WHEREIN A SUSPENSION OF ELECTRICALLY PHOTOSENSITIVE PARTICLES IN AN INSULATING LIQUID MIGRATE IN IMAGE CONFIGUATION WHEN EXPOSED TO IMAGEWISE LIGHT AND, SUBSEQUENTLY, TO ELECTRICAL FIELD. SEPARATION OF THE EXPOSING AND FIELD APPLICATION STEPS IS MADE POSSIBLE BY COATING THE SUSPENSION ON AN ELECTRODE USING A BIASED COATING MEMBER OR BY APPLICATION OF CORONA TO THE SURFACE OF THE SUSPENSION JUST PRIOR TO THE IMAGEWISE EXPOSURE STEP. SUBSEQUENT APPLICATION OF FIELD THEN CAUSES IMAGEWISE PARTICLES MIGRATION.

Abstract: A xerographic plate having a double layered photoconductive portion, the lower layer being designated as a storage layer and the upper layer a control layer. The storage layer consists of halogen doped selenium in a thickness from about 20 to 200 microns. The control layer consists of undoped selenium alloys in a thickness of about 0.1 to 5 microns. The plate utilizes the optimum photoconductive properties of each layer.

Abstract: A development apparatus (200a,200b) for a printing machine (10) having a flexible endless belt (205) entrained around a driven roller (210) and a deflector or protruding member (215). The flexible belt serves as a developer donor member with the protruding member spacing the flexible belt a suitable distance from a latent image bearing photoreceptor (20), so that the latent image is developed by the touchdown development method. Developer is loaded onto the flexible member by any suitable means, such as, a magnetic brush (220). The protruding member locally stretches or bends the flexible belt to cause a reduction in the net force of adhesion of the developer in the locally stretched region of the flexible belt, so that the release of the developer is facilitated to improve the quality of development of the latent images on the photoreceptor.

Abstract: A development system including a developer transport adapted for depositing developer material on an imaging surface having an electrostatic latent image thereon, including a housing defining a chamber storing a supply of developer material including toner. A donor member is mounted partially in said chamber and spaced from the imaging surface, for transporting developer on an outer surface thereof to a region opposed from the imaging surface. The donor member has a magnetic assembly, which includes a plurality of poles, and a sleeve, enclosing said magnetic assembly and rotating about said magnetic assembly. A sensor measures a magnetic field of said donor roll at a predefined position on said donor roll. A magnetic system generates a magnetic field to reduce developer bed height of said developer material on said donor member in a development zone.
