Abstract
A blade cleaning device for removing toner particles remaining on the surface of a photosensitive member after image transfer and which includes a blade which is pressed against the surface and a link supporting mechanism for supporting the blade. In one aspect of the present invention, a spring is provided as connected to the link supporting mechanism mainly to keep the blade in pressure contact with the surface and a coil spring is provided in a node of the link mainly to cancel out any fluctuations imparted to the blade, thereby allowing the blade to be kept in pressure contact with the surface at a desired pressure level at all times. In another aspect, the device is so structured that the blade may be located at an operative position where it is in pressure contact with the surface or at an inoperative position where the blade is separated away from the surface. The device may also be so structured that the blade may be moved sideways in a reciprocating manner while being kept in pressure contact with the surface.
