APPARATUS FOR IMAGE FORMATION ON THE INSIDE OF A CYLINDER

摘要

A roller electrode is positioned in contact with the inside surface of a transparent cylindrical electrode forming a nip. Photoelectrophoretic ink in the vicinity of the nip is exposed to light through the transparent cylinder while a voltage gradient is applied between the electrodes. The image formed on the inside of the electrode is viewed and/or transferred to a web fed axially into the cylinder and deflected toward the image.
