Abstract
An electrophotographic printing machine in which an electrostatic latent image recorded on an imaging surface is developed with toner particles to form a visible image thereof, including a hopper containing a supply of carrier material; a first developer unit for developing the electrostatic latent image with toner particles of a first color; a second developer unit for developing the electrostatic latent image with toner particles of a second color; conduit for connecting the first and second developer unit to the hopper so that carrier material flows to the first and second developer unit; a first feeding system, in communication with the conduit, for regulating the amount of carrier to the first developer unit; a second feeding system in communication with the conduit, for regulating the amount of carrier to the second developer unit, and a controller for controlling the regulation rate of the first and the second feeding system independently.
