ーニング装置。 A photoconductor drum cleaning device for an electrophotographic copying machine, which includes a cleaning roller and a cleaning blade that can be moved toward and away from the photoconductor drum by a common solenoid and a release spring opposing the same. The fixing member is rotatably supported independently around its respective rotation center, and both of these members are biased by a spring so that the cleaning blade is separated from the photoconductor more than the cleaning roller when the solenoid is deenergized. When the solenoid is energized, after the cleaning roller contacts the photoreceptor, the cleaning blade moves against the above-mentioned spring to a position where it contacts the photoreceptor, and the tip of the cleaning blade contacts the cleaning roller during that time. A cleaning device characterized by:
