ABSTRACT:
Piezoelectric properties of materials, such as, polyvinylidene fluoride (PVDF) are used to generate surface potentials that are adequate for the xerographic transfer function. A web of PVDF is used to form a transfer intermediate belt. The magnitude and direction of fields generated around the belt can be controlled by judicious location of field neutralizing devices and the direction, location and magnitude of the belt strain. Toner images are first transferred onto the belt and then transferred from the belt onto copy sheets without the need for high voltage power supplies.
