A new rewritable printing media using electrophoresis and selective heating has been proposed to contribute to the reduction in paper consumption by printers. The mechanism is that when a heated part of the rewritable media is melted, white particles in that part of the media are able to move by electrophoresis. The media is initialized by heating its entire surface under the condition of voltage application and imaging is carried out by selective heating under the condition of an applied reversed-polarity voltage. The relation between Electrophoretic characteristic of TiO2 and the viscosity of the melted wax is discussed.
