Abstract

943,168. Electrophotographic reversal processes. COMMONWEALTH OF AUSTRALIA. Jan. 17,1962 [Feb. 10, 1961], No. 1768/62. Drawings to Specification. Heading G2H. A xerographic recording method comprises exposing a photoconductive insulating layer to electromagnetic radiation imagewise to fatigue the layer differentially, then subjecting the layer to a corona discharge to produce an electrostatic charge image, exposing the charged layer uniformly to reverse the charge image, and developing the said reversed image. Preferably the photoconductive layer is dark-rested before the imagewise exposure which is of greater intensity than the uniform exposure.
