ABSTRACT:
An electrostatic reproducing apparatus comprising a charged particle modulating electrode unit, wherein the common electrode and the control electrode are divided into a plurality of the groups, respectively, in the direction in which the particle passing apertures are arranged. Each of thus divided common electrode groups is disposed in a staggered manner with respect to the corresponding control electrode groups, and the same electric potential is applied to two adjacent common electrode groups opposed to that control electrode group through which a charged particle is to be modulated. The control electrode groups are disposed in such a manner that a boundary between two adjacent common electrode groups is aligned with the center line of the opposed control electrode group. At least one of the surfaces of said charged particle modulating electrode unit is provided with a solid state scanning system of wiring formed integrally therewith.
