ABSTRACT:
A method and apparatus for printing including the use of a pyroelectric imaging member in a novel fashion to produce prints having improved resolution. The prints are produced by thermally exposing the pyroelectric imaging member in a localized fashion while neutralizing the surface charge and subsequently cooling the exposed surface of the imaging member to generate a latent electrostatic image thereon. Subsequently, the latent image is developed with charged toner particles, and transferred from the pyroelectric member to a substrate through the use of a second thermal treatment which serves to reverse the polarity of the imaging member and thereby eliminate the electrostatic forces attracting the toner particles to the imaging member. The transferred toner image may be simultaneously or subsequently fixed to the substrate by a thermal or other well known fusing treatment.
