ABSTRACT:
Disclosed is a process and, to implement the process, an electrostatic charging apparatus comprising means for producing a corona discharge; a counter-electrode positioned below the discharge means adapted for supporting a recording material to be charged; means for supporting the counter-electrode, including a pair of opposed vertical side walls defining a guide channel of substantially rectangular cross-section along which the recording material can pass; and a pair of elongated strip-like members of electrically insulative material extending within the channel at least from the side walls laterally along the opposed marginal regions of the counter-electrode and longitudinally along the whole length of the counter-electrode.
