Abstract
A charge transfer imaging cartridge features driver electrodes extending in a first direction and finger electrodes extending in a second direction and defining edge structure straddling the driver electrodes. The driver and finger electrodes are separated by a flexible dielectric layer, preferably a silicone modified polymer.
