ABSTRACT:
Non-magnetic toner in an electrostatic imaging system, such as the MIDAX.RTM. electronic imaging system, is dynamically recycled. Wayward airborne toner particles in the imaging system are vacuum collected to provide an air stream with entrained toner particles, and a centrifugal separator separates the particles from the entraining air. The separated particles are then dynamically returned to the imaging system. At least one airlock, which may comprise at least first and second fluid actuated or mechanically actuated valves which are spaced from each other, is provided between the separator and a reservoir for toner particles to be supplied to a fluidized bed of toner particles in the imaging system. A distribution device for distributing the toner particles in at least two different horizontal paths, to return to the reservoir.
