Abstract
An electrophotographic charger of the type in which a plurality of corona wires extend in the axial direction adjacent to and separated from the surface of a photosensitive drum in order to charge the surface. A plate-like etching grid is interposed between the corona wires and the drum to ensure the charge is uniformly placed on the drum. The grid is divided into a number of individual removable grids so that the distance between each grid and the adjacent corona wire, and the distance between each grid and the drum surface is substantially uniform.
