Abstract
A corona device suitable for use in electrophotographic apparatus to provide a uniform charge on photoconductive material comprises as the ion-generating means a multiplicity of electrode pins, all of the same diameter, which are provided at the same mutual spacing from one another in a body of insulating material from which all the pins project to the same extent, with the pins limited to a diameter between 10 and 100 microns, a mutual spacing of between 0.3 and 2.5 mm, a projecting length of between 0.7 and 3 mm, a length to diameter ratio of between 10 and 300 and a spacing distance to diameter ratio of between 4 and 250. The electrode pins are formed from lengths of a suitable conductive wire which are laid at the required mutual spacing and soldered to and between conductive strips to form an electrically conductive unit that is embedded in a cast body of the insulating material with free ends of the wire lengths projecting to the required extent.
