An ionizer that acts as an electric charge generating device includes a first high voltage power source and a second high voltage power source, which are disposed in confronting relation to each other, and a first wiring arrangement and a second wiring arrangement, which are disposed in confronting relation to each other. The first high voltage power source applies an AC high voltage to needle electrodes via the first wiring arrangement, whereas the second high voltage power source applies an AC high voltage, which is 180° out of phase with the aforementioned AC high voltage, to needle electrodes via the second wiring arrangement. |
