Abstract
An ion modulating electrode to form an electrostatic image on the image recording member by modulating the ion flow includes a multi-layer structure consisting of a first conductive layer and a first dielectric layer, a second conductive layer, and a second dielectric layer and a third conductive layer, stacked together in that order to form a multi-layer structure, through-apertures formed in this multi-layer structure, and a dielectric or semiconductive thin film coated on the first conductive layer or third conductive layer. A high-frequency voltage is applied between the first conductive layer and the second conductive layer to produce ions in these apertures. A voltage is applied to the third conductive layer for enhancing the passage through the apertures of ions generated in these apertures by high frequency voltage. The thin film covers a part of the inside of the apertures.
