Abstract
A method of and device for recording images on an image-recording medium with a dielectric surface. A voltage is applied in accordance with an image pattern between a set of image-recording electrodes and a companion electrode. Toner powder is deposited on the dielectric surface in accordance with the applied voltage. Image recording is effected by alternately bringing the image-forming electrodes to a positive and negative potential with respect to the companion electrode. According to one specific embodiment, a high-frequency AC voltage is applied during image recording to the companion electrode or at least the image-forming electrodes at times when the latter do not contribute to image forming.
