Abstract
A discharge head for electrostatically recording an image on a recording body including a first insulation layer having a first side and a second side, a plurality of linear extending discharge electrodes disposed on the first side, an induction electrode disposed on the second side, and a second insulation layer disposed to cover all but the tips of the discharge electrodes. The discharge head may also include a insulating substrate layer laminated on the side of the induction electrode opposite the first insulation layer. In addition, the induction electrode may contain a plurality of spaced apart protrusions extending in a direction parallel to the discharge electrodes.
