Abstract

There is disclosed a print cartridge for use in charge transfer imaging comprising first and second electrodes on opposite sides of a layer of dielectric material. The first electrodes extend in a first direction and the second electrodes extend in a second direction, and edge structures are provided in the second electrodes at the locations where the electrodes cross. Various structures are described designed to improve the pattern of charge transfer to a receptor to enhance the accuracy of the image and the efficiency of the transfer.
