Abstract
In an electrostatographic imaging apparatus employing at least one charging device, scorotron which consists of one or more fine wires supported on insulated blocks spaced between the photoconductive surface and a conductive or insulative surface parallel to it. A screen or grid is interposed between the corona wires and the photoconductive surface and the grid is maintained at a potential roughly equal to the potential desired on the photoconductive surface. The scorotrons geometry, the individual wires are from 1/2 to 11/2 inches apart and are spaced from the grid by about 3/4 of an inch. Field enhancement electrode(s) are placed on the screen and are biased at the same potential as the screen. The field enhancement electrode(s) enhance electrical performance.
