ABSTRACT:
To provide an ion generator and an image forming apparatus which control selective ion generation by a voltage lower than the conventional voltage, and are inexpensive and sized as small as possible. In an ion generator which selectively generates ions, ion generation is controlled by temperature control of discharge electrode parts, whereby an ion generator that is inexpensive and sized as small as possible is provided in which discharge electrodes and an electrode are disposed via dielectrics disposed between these, heating elements are provided corresponding to the discharge electrodes, the temperatures of the discharge electrodes are controlled, and an appropriate high voltage is applied between the discharge electrodes and the an electrode, the discharge of the discharge electrodes is controlled by heating of the heating elements, and generation of ions by discharge of the discharge electrodes can be controlled by a low voltage in response to heating control of the heating elements.
