リーニング装置。 A cleaning device for an image forming apparatus that collects residual toner on the surface of a photoconductor using a rotating brush, and has a rotating shaft supported by a cleaning case that expands and contracts in the radial direction around the rotating shaft. A movable displaceable member is provided, and a brush member is attached to the outer surface of the movable member to constitute a rotating brush for collecting residual toner. 1. A cleaning device for an image forming apparatus, characterized in that a cleaning device for an image forming apparatus is provided with an expansion/contraction displacement means for bringing the image forming apparatus into contact with and away from the image forming apparatus.
