ABSTRACT:
A corona discharging device in an electrophotographic apparatus used for discharging or uniformly charging the surface of a latent image bearing member. This discharging device has corona wires to which a voltage of a predetermined polarity is applied and corona wires to which a voltage of the opposite polarity to the predetermined polarity is applied, and alternately applies corona discharges to the image bearing member. Grids are provided between the corona wires and the image bearing member and a common bias voltage is applied to the grids. The final surface potential of the latent image bearing member approaches the grid bias potential.
