Abstract
In an image forming apparatus having a control electrode including gates for allowing toner to pass through them, an image is formed by allowing or disallowing the toner to jump from the toner support to the opposing electrode whilst controlling the electric field near the control electrode elements by applying either 300 V or 0 V to the control electrode from the control electrode voltage source in accordance with image data. Virtual capacitance arising between interconnections associated with the control electrode is limited to or below a predetermined level much lower than the capacitance of the control electrode while the consumed current is maximized under the predetermined conditions.
