A developing unit including a housing having an opening defining a developing zone, an applicator for applying particulate developer through the opening towards an electrostatographic image to be developed, and a paddle wheel for agitating developer within the housing, for scooping up developer from within the housing and projecting scooped-up developer towards the applicator. A hopper, located outside the width of the development zone supplies toner to the housing, and a primary spiral screw conveys developer from the hopper across the width of the development zone in one direction, while a secondary spiral screw receives developer from the primary spiral screw and conveys developer across the width of the development zone in an opposite direction. A passageway outside the width of the development zone enables the return of developer from the secondary spiral screw to the primary spiral screw.
