Abstract

Grid wires arranged in an axial direction of a photoconductive drum have a positional relation with projecting electrodes arranged at regular intervals in an axial direction of the photoconductive drum at a position opposite to the surface of the photoconductive drum wherein the grid wires and the projecting electrodes positioned adjacent to each other are equally arranged in distance to uniformly discharge an electric charge to the surface of the photoconductive drum from each of the projecting electrodes so that uniform charging can be accomplished in an axial direction of the photoconductive drum.
