ABSTRACT:
An electrophotographic copying apparatus has a frame with two portions which are movable away from each other. An electrophotographic photoconductive member is mounted on one of the frame portions for being exposed when the frame portions are moved away from each other to enable the member to be removed from the frame. A blade-type cleaning device is provided having an elastic blade member for contacting the surface of the electrophotographic photoconductive member for removing residual toner from the surface during movement of the member and a blade holder holding the blade member and mounted on the one frame portion for movement toward and away from the surface of the electrophotographic photoconductive member. A spring is connected to the holder for biasing the holder to urge the blade member into contact with the surface when the frame portions are together. A retracting device is connected to the cleaning device for retracting the holder from the surface when the frame portions are moved away from each other.
