A support structure located in the interior of an electrophotographic copier photoconductive drum to guide removal of the drum from its rotational shaft while eliminating potentially injurious radial movement, has extender guides which can protrude from the end of the drum to provide an effective continuation of the guiding surface provided by the support structure. Each guide, upon which the inner surface of the drum will ride during removal, can, during normal operation of the copier, be held in an inoperative position within the drum interior. The outwardly protruding ends of the guides also can be beveled or tapered to facilitate reinstallation of the drum into its operating position within the copier.
