An apparatus for simultaneously fluidizing, charging and loading toner onto a donor member in one step using a corona device which is enclosed and separate from the toner supply. An ion-air stream emanating from this charging device also directs the charged toner onto the donor. The system includes a housing for containing toner particles; a donor member, mounted in said housing, for transporting charged toner particles on the surface said donor member to a development zone adjacent to said image bearing member; a loading system for loading said donor member with charged toner particles, said loading system includes blower for generating an air stream for fluidizing toner particles and charging device for charging said air stream.
