ABSTRACT:
A cleaning device for use in an electrostatic copying machine removes with a blade any residual toner from a photosensitive body after a toner image has been transferred therefrom to a sheet of copying paper. A support shaft supports the blade for slidable contact with the photosensitive body and has a horizontal axis extending perpendicularly to a direction of travel of the photosensitive body. The support shaft is angularly movable about the axis and is axially movable. A rotational shaft is rotatable about an axis parallel to the support shaft. A first device converts rotational movement of the rotational shaft into reciprocal movement along the axis of the support shaft. A second device converts rotational movement of the rotational shaft into reciprocal angular movement of the support shaft. A third device releases interconnection between the rotational shaft and the first and second devices.
