Abstract
A replenisher for facilitating flow of toner in an electrophotographic apparatus. The replenisher includes a sump for receiving the toner. An beater element having a plurality of blades is rotatably mounted within the sump wherein some of the blades impart a shear force and a normal force along the axis of rotation to the toner while others of the blades impart a shear force and a normal force towards or away from the axis of rotation to the toner as the beater is rotated through the toner. This effectively 'aerates' the toner and keeps it mobile within the sump.
