Abstract

An electrostatic latent image forming plate having a conductive layer on an insulating substrate is employed. The conductive layer is removed in the form of the image to be obtained to make on the insulating substrate recessed portions having an insulating bottom surface in the form of the image. The image forming plate having the insulating recessed portions is subjected to a corona discharge made by a corona charger. In the corona charging region in which the image forming plate is subjected to the corona discharge, the conductive layer is grounded by a grounding means provided in contact with the surface of the image forming plate. By the grounding means, the potential of the isolated conductive parts of the image forming plate is lowered to prevent the discharge between the isolated conductive parts. In the apparatus for forming an electrostatic latent image on the image forming plate having insulating recessed portions, grounding wires or grounding rollers which are grounded are provided in contact with a drum or an endless belt on which the image forming plate is carried so that the surface of the conductive layer of the image forming plate may be grounded thereby.
