Abstract
A blade cleaning apparatus, process, and reproducing machine are provided for removing residual particulate material such as toner from the surface of an electrostatic imaging member. Improved cleaning particularly with respect to developer side seal failures is obtained by rapidly vibrating the blade during cleaning. Means can be provided for selectively activating the vibration of the blade so that vibration may be applied only after the imaging member is stopped or during movement of the imaging member and for a short time after it has stopped. In accordance with an alternate embodiment, the blade is vibrated so that the edge of the blade which contacts the surface of the imaging member has a vibrational velocity which is greater than the surface velocity of the imaging member.
