A drum covered by a photoconductor is used in the electrophotographic process of a copier or printer. In this design, the drum is encircled by a sheet of photoconductor starting from a supply roll within the drum and terminating at a take-up roll within the drum. The photoconductor on the surface of the drum can be replenished from the supply roll, and the used photoconductor wound onto the take-up roll. The photoconductor is manually advanced, tensioned, and sealed by a simple mechanism that can be used in a small drum and allows ample space for stored photoconductor. In the figures, the photoconductor 12 follows a path from supply roll 10, through the sealed slot 19 to the surface of the drum, around the drum, back through the sealed slot 19, and then to the take-up roll 13.
