Both charging and discharging devices (16, 26, 28, 48) for an electrostatic xerographic and other types of electrophotographic copiers or printers are constructed in the form of a filament brush (30), the fibers of which are each electrically conductive and connected to a potential voltage source whereby the individual fiber tips (33) will function as a corona discharge source to charge or discharge the photoconductive surface of an electrostatic copier but with substantially reduced power requirements. |
