ABSTRACT:
A method is disclosed for copying a graphic representation using a uniformly poled pyroelectric material.
The uniformly poled pyroelectric material is selectively heated to form a differential charge pattern on the material. The differentially charged material can be used with charged toner particles to form a copy of the graphic representation using techniques well known in the art.
