Abstract
A drum for an electrophotographic copier which serves as an intermediate image carrier which drum is rotatably mounted in the copier and includes a takeup roll and a supply roll with photoconducting material, in the form of a web, being guided from the supply roll over a deflection roll outwardly to the surface of the drum and over a second deflection roll to the takeup roll. The takeup roll is adapted to be coupled to a drive motor disposed outside of the drum for a stepwise feed of the photoconducting material. The drum is rotatably mounted by two pins with one of the pins being rotatable circumferentially relative to the drum and being non-rotatably connectable with a gear meshing with a further gear mounted on the takeup roll. The one pivot pin is connected by a freewheel mechanism to a drive motor which, in normal operation, drives another component of the copier with the rotational direction of the drive motor being reversible in order to drive the one pivot pin.
