摘要:
This disclosure comprises the recording and/or storing of information received in the form of electrical signals by scanning and illuminating at least a portion of the surface of a PIP material with a constant intensity radiation beam and applying a varying potential to the illuminated surface in accordance with the electrical signals so as to selectively polarize the PIP material. PIP material is used herein is defined as any material capable of exhibiting ''''persistent internal polarization'''' under the influence of radiation and an applied electric potential.

D R A W I N G A PERSISTENT INTERNAL POLARIZATION (PIP) ELECTROPHOTOGRAPHY PRINTING OR COPYLING SYSTEM COMPRISING STATIONARY ELECTRODES WHICH ARE NOT REMOVED DURING DEVELOPMENT, AND WHEREIN AT LEAST ONE ELECTRODE IS OF A DISCONTINUOUS CONFIGURATION, SUCH AS A FORAMINOUS CONDUCTIVE MESH, WHICH IS EMBEDDED IN OR ATTACHED TO THE SURFACE OF THE PIP LAYER WHICH IS TO BE TONED (THE TOP LAYER), SUCH THAT AN ELECTRIC FIELD CAN BE APPLIED TO THE PIP LAYER WHILE PERMITTING RADIATION TO REACH THE PIP LAYER, AND WHEREBY TONING AND TRANSFER MAY BE ACCOMPLISHED WITHOUT REMOVING EITHER ELECTRODE.

THERE IS DISCLOSED A REUSABLE IMAGE PANEL DEVICE FOR PRACTING ELECTROPHOTOGRAPHY. THE PANEL ISCOMPOSED OF A CONDUCTIVE TRANSPARENT ELECTRODE, A PHOTOCONDUCTIVE LAYER, AN OPAQUE LAYER, A LAYER OF LIQUID TONER, AND A SECOND ELECTRODE. THERE IS FORMED AN IMAGE ON THE OPAQUE LAYER BY ELECTROPHORETIC DEPOSITION OF TONER PARTICLES IN IMAGE CONFIGURATION.
