ELECTROGRAPHIC RECORD MEDIUM

摘要

For use in an electrostatic recording system with voltage charging apparatus having charging electrodes, an electrographic record medium is provided having spacer means, a portion of which projects above the outer surface of a dielectric layer of the record medium. The spacer means space the outer surface of the dielectric layer from the charging electrodes during the voltage charging of a defined area of the outer surface of the dielectric layer.
