ABSTRACT:
An apparatus for developing a latent image recorded on a surface, including a housing defining a chamber storing a supply of developer material including toner; a toner donor member spaced from the surface and being adapted to transport toner to a region opposed from the surface, the donor member having an electrode member associated therewith; developer material is conveyed in the chamber of the housing onto the donor member; a first AC source for AC biasing the electrode member; and a second AC source for AC biasing the electrode member with an AC rectified waveform, said first and second AC source coacting to detach toner from said donor member as to form a toner cloud for developing the latent image.
