A cartridge for use in charge transfer imaging comprising a flexible dielectric substrate carrying sets of driver electrodes and finger electrodes, the electrodes being separated by a dielectric layer. The respective electrodes extend in different directions to form a charge generating matrix in a first central portion generally corresponding to the extent of the dielectric layer. Each of the electrodes has individual contacts which extend to the sides of the dielectric layer. The flexible substrate is deformable from its natural planar form to a U-shape, the charge generating matrix and the dielectric layer being located on a first central portion of the substrate, and the contacts of the electrodes being located on second and third side portions of the substrate. A method of manufacturing the cartridge is also disclosed.
A print cartridge for use in charge transfer imaging, comprising:
In a cartridge for use in charge transfer imaging having a dielectric substrate fixed to a spine, first electrodes printed on the substrate and having parallel conductors extending generally longitudinally and individual contacts extending generally transversely from ends of the conductors, a dielectric layer covering at least the parallel conductors so that the conductors are at a first side of the layer, and second electrodes at the opposite side of the dielectric layer defining edge structures straddling the parallel conductors of the first electrodes and having individual contacts to the side of the parallel conductors, the improvement in which:
