Abstract
An electrostatic latent image forming device has at least two electrodes with an insulating layer formed between the two electrodes. The electrodes are arranged in a matrix array. One set of electrodes has space regions formed in the electrodes in which creeping corona discharge occurs when a voltage is applied to those electrodes. The insulating layer between the electrodes is formed of a ceramic material. A third electrode is used to draw the ions out of the apertures of the electrodes. A ceramic insulating layer is placed between the electrodes with the apertures and the third electrode.
