Abstract
An electrophotographic copying machine in which the drum is rotatable about a given axis and is at least partly formed by a plurality of sectors each having a surface constituting part of the cylindrical periphery of the drum and each being mounted within the drum as to be slidable in a direction perpendicular to the said axis between a first position in which it defines the respective part of the cylindrical periphery of the drum, and a second position into which it is shifted radially with respect to the remainder of the cylindrical periphery; each of the sectors has a portion of a photoconductive band wound around its surface and extending from a feed reel to a take-up reel; these reels are mounted inside the respective sector and reversible locking means are provided for maintaining the sectors in their first position during the rotation of the drum about the said axis.
