Abstract
A cleaning device in an electrostatic copying apparatus, for removing residual toner particles from the surface of a photosensitive member adapted to move through an endless conveying passage, includes a blade holding mechanism mounted pivotally around an axis extending substantially parallel to the surface of the photosensitive member and substantially perpendicular to the moving direction of the photosensitive member, and a cleaning blade mounted on the blade holding mechanism. The cleaning device further includes a first spring elastically biasing the blade holding mechanism to a non-operating position in which the cleaning blade is away from the surface of the photosensitive member and an operating mechanism selectively positioning the blade holding mechanism against the elastic biasing action of the first spring to an operating position in which the cleaning blade is pressed against the surface of the photosensitive member. The operating mechanism includes a clutch with an input drivingly connected to the photosensitive member drive system, a cam, a cam follower, and a power transmission arrangement for transmitting power from the cam to position the blade holding mechanism so that the cleaning blade is pressed against the surface of the photosensitive member. The power transmission arrangement includes a first power transmission member, having an input terminal on which the cam acts, and a second power transmission member, having an output terminal acting on the blade holding mechanism.
