Method and apparatus for reducing residual toner in a rotating container

An image forming device comprising:

• an image marking device;
• and
• at least one rotating toner delivery container, the at least one rotating toner deliver container comprising:
• a rotatable vessel configured to contain a toner, the rotatable vessel comprising a body section having a substantially round cross-section, a first end at one axial end of the body section, a second end axially distal the first end, and helical features on an internal surface of the body section configured to transport at least a portion of the toner in an axial direction into the image marking device, the axial direction being between the first end and the second end as the rotatable vessel is rotated;
• and
• an insert configured to tumble and rotate within an inside portion of the rotatable vessel and agitate the toner as the rotatable vessel rotates.

A method of filling a container with a toner material useful in printing, the method comprising:

• providing a vessel configured to contain a toner, the vessel comprising a body section having a substantially round cross-section, a first end at one axial end of the body section, a second end axially distal the first end, and helical features on an internal surface of the body section, the helical features being configured to transport the toner in an axial direction between the first end and the second end as the vessel is rotated by an image forming device;
• causing, at least in part, the vessel to be filled with the toner;
• and
• causing, at least in part, an insert configured to agitate at least a portion of the toner to be input into the vessel, the insert being configured to tumble and rotate within an inside portion of the vessel as the vessel is rotated by the image forming device.
