Abstract
In an electrophotographic copier including a replaceable photoconductive sheet having a leading edge portion and a trailing edge portion and a guide drum rotatably supported by a drum shaft and having a circumferential surface for supporting the sheet and a holding device for securing the leading sheet edge portion to the guide drum, the holding device is composed of elements defining a wedge-shaped slot disposed alongside the circumferential surface of the drum and delimited by a pair of faces which converge toward the circumferential surface where they form an insertion opening for a photoconductive sheet, a wedge loosely disposed in the wedge-shaped slot, and an element urging the wedge toward the insertion opening for clamping a photoconductive sheet end inserted in the slot between the wedge and one of the faces.
