<p>PURPOSE:To easily manufacture an ion flow-control recording head as well as obtain uniform electrostatic latent images by making up at least any one of an upper control electrode and a lower control electrode from wires set on an ion flow-control holes. CONSTITUTION:Ion flow-control holes 4 of a diameter of 100-500mum are drilled in an insulator base plate 9 by laser processing, etc., and at least one of upper and lower control electrodes 5 and 6 made of small wires 11 is bonded onto the holes 4 by wire bonding method to form a matrix ion-flow control recording head. In the case of matrixing drive, ion flow is passed through only the ion- flow control hole 4(1,3) under the conditions of 4kV corona wire voltage and 0V counter electrode voltage by applying 200V to the upper control electrode 5i 120V to the lower control electrode, and 250V to the others. The manufacturing errors between the ion flow-control holes can thus be lessened and the holes can be closely arranged.</p> |
