Abstract
The invention provides a method of making an ionographic cartridge for use with a dielectric coated drum to lay electrostatic images on the drum for subsequent toning. The method includes the steps of making a printed circuit board carrying on one of its faces a plurality of driver electrodes; attaching to the face of the board a dielectric layer sufficient to cover the driver electrodes; providing finger electrodes supported individually between parallel strips of dielectric tapes; and adhering the finger electrodes to the dielectric layer with the finger electrodes straddling the driver electrodes and the tapes spaced to either side of the printed circuit board.
