Apparatus for charging a substrate and an image forming apparatus comprising an apparatus of this kind

摘要

An apparatus for charging a substrate including a dielectric substrate, a support member having a first end and a second end between which said member extends substantially parallel to said substrate, a row of electrodes distributed over the support member between the first and second ends, said electrodes extending from the support member in the direction of the substrate, the electrodes having a free end for spraying a charge on the substrate, each free end having a substantially fixed distance from the substrate, wherein the distance in the case of the electrode located at the first and second end of the support member differs substantially from the distance in the case of the electrode located in the middle of the support member.
