Abstract

PURPOSE: To enable to obtain a good latent image of a quality image and discharge for reproduction by rendering the distance between a wire electrode for corona charge to 1,5W10 times as much as the distance the wire electrode and a shield, and inserting a resistor between the shield and a grounded electrode.
