An electrophotographic copier includes a replaceable photoconductive sheet having a leading edge portion and a trailing edge portion; a guide drum rotatably supported by a drum shaft and having a holding device for securing the leading sheet edge to the guide drum; a charging station, an illuminating station, a developing station, a transfer station and a conductive sheet cleaning station arranged in a circumferential distribution about the guide drum. The leading edge of the photoconductive sheet is attached to the guide drum and, upon rotation of the guide drum, a pressing roll, brought into engagement with the guide drum by a control mechanism, presses the trailing edge of the photoconductive sheet on the leading edge, as a result of which, by means of an interposed adhesive, the photoconductive sheet is bonded together to form an endless band about the guide drum. The control mechanism is actuated by one of the processing stations arranged about the guide drum, so that when such processing station is moved into an open position providing access to the photoconductive sheet, the pressing roller is automatically lowered onto the guide drum and, conversely, when the processing station is moved into its closed position, the pressing roller is automatically lifted off the guide drum.

A cleaning device for wiping the cylindrical face of a roll supported for rotation has an elongated frame comprising a plurality of elongated support webs oriented at an angle to one another in a star-like configuration; a cleaning felt secured about the frame and supported by the free longitudinal edges of the support webs; pressing levers movably supported adjacent the roll and including a frame supporting arrangement for rotatably holding and positioning the frame at opposite ends thereof, parallel to the axis of the roll; and a spring connected to the pressing levers for urging the pressing levers towards the roll for pressing the frame against the roll into a working position. The cleaning felt is divided into a plurality of cleaning felt portions by any two neighboring free longitudinal edges. In the working position, one of the cleaning felt portions is urged into a shape-conforming engagement with the cylindrical face of the roll along the length thereof.
