Abstract
In an image forming device an apparatus is provided that supplies a continuous flow of an electrical charge between a photoconductive drum and a power supply. In one embodiment, an electrically conductive member receives a shaft of the photoconductive drum. An electrically conductive cap disposed on a first side of the electrically conductive member, aligned with an aperture of the electrically conductive member, and capable of being electrically coupled with the shaft via the electrically conductive member. There is also an electrically conductive resilient member having a leading end and a trailing end electrically couple with the electrically conductive member and the shaft in a manner that the leading end is disposed on the first side of the electrically conductive member and the trailing end is disposed on the second side of the electrically conductive member with at least a portion of the trailing end extending across the aperture of the electrically conductive member.
