ABSTRACT:
A latent electrostatic image is formed on an electrophotographic member having a crystalline, stable coating of wholly inorganic photoconductive material which is of the order of 0.2 to 2 microns thick. This is effected by moving a corona needle energized by a corona power source and a laser beam modulated from digital information together over the photoconductive coating in a progressive manner at high speed. The latent electrostatic image so formed is then developed.
