ABSTRACT:
In an electrostatic image recording apparatus employing a series of recording styluses for forming a latent image on an electrostatic image recording drum, an over-discharge is conducted either by applying a very high voltage to the recording styluses or by first subjecting the drum to a pre-charge in one polarity and then forming the latent image on the drum by an over-discharge in the opposite polarity. Pre-charging of the drum enhances the effect of the subsequent discharging and permits over-discharge to be conducted with a lower voltage applied to the recording styluses than would otherwise be possible.
