PURPOSE:To improve the utilization efficiency of generated ions and to reduce ozone production by generating ions over the entire discharged area covering the nearly entire surface of a discharging electrode except the jointing surface with a dielectric, and sticking the generated ions on a body to be removed and charged electrostatically and removing or charging electrostatically the object body. CONSTITUTION:An electrostatic discharging device 1 has the dielectric 2, an induction electrode 3, and the discharging electrode 4 and an alternating voltage is applied from an alternating voltage power source 8 to between the discharging electrode 4 and induction electrode 3. Electrostatic discharge is caused in the discharge area 10 of the dielectric 2 on the side of the discharging electrode 4 to generate positive and negative ions. In this case, the discharge area is not only nearby the side end surface of the discharging electrode 2, but also nearby the surface of the discharging electrode 4 which faces the member 5 to be charged electrostatically, and ions are generated. Then, only ions determined by the polarity of a DC bias power source 9 between the positive and negative ions move to a recording layer 6 with a DC bias voltage applied between the discharging electrode 4 and a conductive substrate 7. |
