Abstract
A helical auger member for transporting toner in an image forming apparatus. The auger member may be implemented as part of a waste toner removal system for removing toner from a photoconductive member of a toner cartridge. Toner that is removed by a cleaner member is transported through a cleaner housing with a helical member, such as a coil wire, having a pitch to outer diameter ratio from about 1.5 to 2.5.
