This invention provides an agitator blade (250) and toner cartridge (100) employing such an agitator blade (250). The blade (250) consists of an axially directed axle shaft (124) having a plurality of rigid, radially directed ribs (320, 322, 324, 326, 328) that extend to a location proximate to the inner wall of the tank. A plurality (330) of cross bar members are mounted, between each pair of ribs. Each cross bar includes axially extended, rib-engaging wings (740). The wings are mounted so that the cross bars are generally prevented from passing between the ribs when the cross bars are driven by the ribs in the normal direction of agitator rotation. However, the wings are sufficiently resilient so that a predetermined level of toner resistance at high fill levels causes the wings and cross bars to elastically deform and pass through the ribs, leaving only the thinner ribs to traverse the toner in that cycle.
