ABSTRACT:
The present invention provides a toner container system, such as a toner cartridge, comprising a housing including a first reservoir for containing toner and a second reservoir for receiving toner from the first reservoir and transferring the toner to an image forming apparatus, and a toner transfer mechanism that includes a rotatable roller member having in the surface thereof a recess defined by a concave surface having a radius of curvature, and wherein the roller member is rotatable from a first position at which the recess is open to the first reservoir and a second position at which the recess is open to the second reservoir, for conveying toner from the first reservoir to the second reservoir upon rotation of the roller member from the first position to the second position, and a rotatable wiper member disposed within the second reservoir and being sized and having a flexible distal end rotatable through the recess in contact with the concave surface when the roller member is in the second position.
