摘要：An electrostatic latent image forming plate having a conductive layer on aninsulating substrate is employed. The conductive layer is removed in the form of theimage to be obtained to make on the insulating substrate recessed portions having aninsulating bottom surface in the form of the image. The image forming plate having theinsulating recessed portions is subjected to a corona discharge made by a coronacharger. In the corona charging region in which the image forming plate is subjected tothe corona discharge, the conductive layer is grounded by a grounding means provided incontact with the surface of the image forming plate. By the grounding means, thepotential of the isolated conductive parts of the image forming plate is lowered toprevent the discharge between the isolated conductive parts. In the apparatus forforming an electrostatic latent image on the image forming plate having insulatingrecessed portions, grounding wires or grounding rollers which are grounded areprovided in contact with a drum or an endless belt on which the image forming plate iscarried so that the surface of the conductive layer of the image forming plate may begrounded thereby.
