ABSTRACT:
A device for transferring charged developing particles onto an electrostatic latent image, comprising a reservoir for holding a quantity of developing particles, a multilayered developing roller rotatably exposed to the quantity of developing particles, including a surface layer for frictionally charging the developing particles with a specified polarity and for attracting the charged developing particles for forming a coating of charged developing particles on the surface layer, and an image carrier for supporting the electrostatic latent image in proximity to the developing roller, the latent image having a polarity opposite to the specified polarity for attracting the charged developing particles from the coating onto the latent image.
