Abstract
The present disclosure relates to a device and/or method for conveying a quantity of image forming material between selected regions in a printing device or printer cartridge. A roller is provided having a surface that may include a recess capable of transferring a quantity of image forming material. The recess may include a convex surface. A wiper is configured to engage at least a portion of the roller surface and/or the convex surface in the recess to assist in the removal of image forming material that may otherwise accumulate on the roller surfaces. Such roller design and wiper configuration may therefore cooperate to improve the consistency of image forming material transfer.
