ABSTRACT:
An electrophoretic recording apparatus for use with a developer having charged pigment dispersed in a dispersion medium which includes a plurality of electrical field generators for selectively applying a voltage across the developer fed onto the recording paper. Each electric field generator includes a recording electrode and opposed electrode provided on opposite sides of the recording paper. The recording electrode includes a main electrode and an auxiliary electrode dispersed about the main electrode to suppress spread of the electric field and yield recording of higher resolution.
