Abstract
A printer cartridge is provided that allows a charge roller to be separated from a photoconductive drum when the printer cartridge is not used within an image forming device. The printer cartridge includes the photoconductive drum, the charge roller, and a separating member having a resilient member disposed thereon with the separating member being disposed on the charge roller. The separating member engages and disengages the photoconductive drum in a first position and in a second position. The first position provides a spaced relationship between the charge roller and the photoconductive drum and the second position provides an engaged relationship between the charge roller and the photoconductive drum. The printer cartridge also includes the photoconductive drum disposed adjacent to the charge roller in an offset orientation that includes a centerline of a charge roller shaft offset by a predetermined distance from a centerline of a photoconductive drum shaft.
