Abstract
An improved electrographic apparatus employing a photosensitive drum of a foil-shaped photosensitive body wound around a disc shaped frame. The drum is inserted into and removed from the electrographic apparatus body and there are first and a second bar-shaped members secured to opposed peripheral edges of the foil-shaped photosensitive drum and engaged with said disc-shaped frames, respectively. Current supply rings are concentrically arranged on and secured to the outer surface of one of the disc-shaped frames, the foil-shaped photosensitive body is provided with an electrically conductive substrate connected through a first of the bar-shaped members and a tension spring and one of the current supply rings to a bias voltage source. The electrically conductive layer of the foil-shaped photoconductive body is connected through a lead wire, an electrically conductive member embedded in the disc and the other current supply ring to the bias voltage source.
