Process for forming an ion producing device

摘要

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.
