A power supply for transmitting voltage to a device, including a web having a piezoelectric exterior layer for generating a voltage on the surface thereof in response to being deformed. The web is entrained about a roller arrangement to deform the piezoelectric exterior layer. Commutation brushes transfers the voltage generated on the surface of the piezoelectric exterior layer to the device. The roller arrangement in combination with the placement of commutation brushes and neutralization brushes are used to adjust the voltage to the device.

High voltage power supply

A toner composition comprised of resin, pigment or dye particles, and a quaternary ammonium bisulfate charge enhancing additive of the formula R'.sub.2 R'.sub.2 N.sup.+ X- wherein R' and R' are independently selected from the group consisting of alkyl, aryl, and alkylaryl; and X- is a bisulfate anion.

Toner and developer compositions with charge enhancing additives

A photosensitive member having at least two electrically operative layers. The first layer comprises a photoconductive layer which is capable of photogenerating and injecting photo-excited holes into a contiguous active layer. The active layer comprises a transparent organic material which is substantially non-absorbing in the spectral region of intended use, but which is 'active' in that it allows injection of photo-excited holes from the photoconductive layer, and allows these holes to be transported through the active layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light, and development.
