ABSTRACT:
An apparatus in which an electrostatic latent image recorded on a photoconductive member is developed. A supply of developer material comprising at least toner particles and carrier granules is stored and transported closely adjacent to the electrostatic latent image recorded on the photoconductive member. The quantity of developer material being transported to the electrostatic latent image recorded on the photoconductive member is controlled by a metering blade. At least accumulation of toner particles adjacent the blade is prevented and a flow of toner particles away from the blade induced. In this way, the escape of toner particles from the storage chamber thereof is substantially minimized.
