Abstract

An apparatus in which particles are moved from one end of a duct to the other end thereof. The particles in the duct are fluidized. A pressure differential is generated which moves the fluidized particles in the duct from one end of the duct to the other end thereof. When the particles pack and cake together, the apparatus automatically moves the toner particles away from the region of the packed and caked toner particles to relieve this condition.
