Abstract
1339957 Electro-photography EASTMAN KODAK CO 19 April 1971 [9 March 1970] 23155/71 Heading G2H The photo-conductive layer of a travelling web 12 comprising a conductive layer between photoconductive and insulative layers is charged by corona device 30, exposed at station 22, developed by passage through bath 24 having development electrode 23, and reverse charged by corona device 30' of adjustible potential so as to provide a bias potential gradient along the conductive layer.
