ABSTRACT:
An apparatus which develops an electrostatic latent image recorded on a photoconductive member with toner particles. A donor member is spaced from the photoconductive member and transports toner particles to a development zone adjacent the photoconductive member. Electrode wires are positioned in the development zone between the photoconductive member and the donor member. The electrode wires are electrically biased to detach toner particles from the donor member to form a cloud of toner particles in the development zone. Toner particles detached from the toner particle cloud develop the latent image. The electrode wires are adjustably supported in tension adjacent the donor member.
