<p>A corotron for use in electrostatographic reproducing apparatus, which produces uniform charge along the length of the device comprises a plurality of parallel coronode wires (44, 46) supported between insulating end block assemblies (42, 43). The coronode wires, made for example of tungsten oxide, are closely spaced, e.g. less than 0.2 inches apart such that, when energized, each wire is within the electrostatic fringe field of the adjacent wire. Two wires may be formed from a single U-shaped wire with a closed end portion wrapped around an arcuate insulating end post (54) in a first end block assembly (42). The free ends of the coronode wire may be wrapped around a further arcuate insulating end post (55) in the second end block assembly (43). Insulating block adapters (48) having wire positioning slits (49) therein are preferably included at both ends of the device, the end posts (54, 55) being larger in diameter than the width of the slits whereby the wires are urged against opposite sides of the slits. A conductive shield (40) may be included which extends between the supporting end block assemblies.</p> |
