ABSTRACT:
There is disclosed an electrostatic recording apparatus comprising a plurality of wire electrode groups each constituting a block, the corresponding wire electrodes of the respective groups being simultaneously scanned, a pair of auxiliary electrode rows arranged respectively along both sides of and in opposite to the wire electrode groups, the auxiliary electrodes of one row being positioned in a zigzag form relative to those of the other row and each of the auxiliary electrodes having approximately the same length as the width of one block of the wire electrodes, and means for scanning the auxiliary electrodes at a predetermined phase difference. The recording by one wire electrode group is performed by applying respective recording voltages or currents between the one wire electrode group and ones of the auxiliary electrodes opposite thereto.
