Abstract
A developer storage and delivery system for liquid electrophotography having:(a) an insulating substrate with a first surface and a second surface;(b) a plurality of discrete conductive heating elements mounted on the first surface; and(c) a phase change developer having a melting point of at least 22° C.,wherein the phase change developer is on the top surface of each of the discrete conductive heating elements, except that a small portion of both ends of each of the conductive heating elements is free of the phase change developer for conducting electricity.
