の回転制御装置。In an electrophotographic copying machine or the like in which a void surface is provided at an appropriate location on the surface of the photoreceptor, and a reflective paper jam detection sensor is disposed on one outer periphery of the photoreceptor, a void surface is provided at an appropriate location near the void surface of the photoreceptor. A convex portion is provided, and a photoconductor stop position sensor that detects the stop position of the photoconductor by the convex portion is arranged on one outer periphery of the photoconductor, so that the void surface of the photoconductor stops at the position where the paper jam detection sensor is placed. If this happens, when restarting the machine, the void surface of the photoconductor will be forcibly moved from the position where the paper jam detection sensor is placed, and the machine will become unusable due to false paper jam detection due to the void surface. A rotation control device for a photoreceptor in an electrophotographic copying machine, etc., which prevents this from occurring.
