Abstract
A multi-pin-electrode electrostatic recording system includes a recording head having 2048 pin electrodes aligned in a line and 65 pairs of auxiliary electrodes positioned near the pin electrodes. A negative recording pulse is applied to a selected pin electrode when a positive recording pulse is applied to a corresponding pair of auxiliary electrodes to form an electrostatic latent image on a dielectric layer of a recording paper. A compensation negative voltage pulse is applied to the auxiliary electrodes, the compensation negative voltage pulse having a pulsewidth longer than the positive recording pulse and the positive recording pulse being superimposed on the compensation negative voltage pulse. By the compensation negative voltage pulse, the occurrence of the ghost image on the non-selected image point is eliminated.
