ABSTRACT:
A photoelectrophoretic imaging apparatus in which a disposable, electrically biased blocking web has a portion thereof in contact with a moving heated member. A disposable imaging web, electrically biased to a polarity opposite to the polarity of the blocking web, contacts the heated portion of the blocking web. Photosensitive particles dispersed in a normally solid waxy binder matrix are interposed between the imaging web and the blocking web. A light image is projected onto the heated portion of the imaging web contacting the blocking web causing selective migration of the photosensitive particles in the liquefied waxy binder matrix in image configuration.
