Abstract
A photoconductor unit for an electrophotographic image forming device according to one example embodiment includes a housing and a photoconductive drum rotatably mounted on the housing. The photoconductive drum includes a drive coupler that is positioned to mate with a corresponding drive coupler of the image forming device to receive rotational and axial force therefrom for rotating and axially biasing the photoconductive drum when the photoconductor unit is installed in the image forming device. A wear member is positioned to receive frictional contact from a portion of the photoconductive drum in a direction of the axial bias on the photoconductive drum such that as the photoconductive drum rotates, the frictional contact on the wear member gradually wears away the wear member in the direction of the axial bias on the photoconductive drum thereby gradually shifting the photoconductive drum axially in the direction of the axial bias.
