Abstract
An electrostatic charge emitting apparatus includes a discharging member having an electrode member, an electrically conductive elastic rubber member having fine conductive particles contained therein and an insulating layer having a number of apertures therein and being formed on the conductive elastic rubber member; and the electrode member is connected to an electric power source and a surface of the insulating layer is urged against a member to be charged or de-charged: and the member to be charged or de-charged is charged or de-charged by discharge in the apertures of the insulating layer generated by emitting electrostatic charge toward the member at a lower threshold voltage and thus the generation of ozone gas can be decreased.
