Abstract
An approach is provided for reducing an amount of residual toner remaining in a rotating container. The approach involves rotating a rotatable vessel configured to contain a toner. The approach also involves a causing a plurality of beads that include at least one material configured to be attracted to a magnetic strip that extends in a direction parallel to an axial direction of movement of the toner between a first end and a second end of the vessel. The plurality of beads, when attracted to the magnetic strip, cooperate with helical features of the vessel and the internal surface of a body section of the vessel to transport at least a portion of the toner in an axial direction from the first end of the vessel to the second end of the vessel as the vessel is rotated.
