An apparatus in which an auger, coupled to a hopper storing toner particles, dispenses toner particles substantially uniformly into a developer mixture. The auger comprises a tubular member having a plurality of apertures therein for discharging toner particles therefrom. A toner transport is disposed interiorly of the tubular member for advancing the toner particles therealong. The toner transport has a helical tooth for advancing the toner particles along the tubular member. The helical tooth has sections thereof deleted therefrom in the region of the apertures in the tubular member to facilitate discharging of the toner particles from the toner member and to prevent caking and clogging thereof.
