ABSTRACT:
In an image forming apparatus for forming a static latent image using ions as a medium, an ion generation formed by stacking a plurality of line electrodes, a plurality of finger electrodes, and a screen electrode with dielectric layers being sandwiched therebetween is arranged to oppose a dielectric drum on which the electrostatic latent image is to be formed. A static induction transistor for switching an RF high-voltage signal at a high speed is connected to each line electrode of the ion generator. Each static induction transistor is also connected to a DC high-voltage power source via a coil. When each static induction transistor is driven at a high frequency by a source drive circuit, an RF high voltage is applied to a corresponding line electrode. A voltage is supplied to a parallel resonator constituted by the coil and a line electrode capacitance to start resonance, thereby obtaining an output for ion generation.
