摘要： An apparatus for cleaning residual toner from the photosensitive surface of the rotating drums of photocopying machines. The cleaning assembly includes at least a cleaning roller and a cleaning blade which are moveable from an inoperative position spaced away from the photosensitive surface to an operative position in contact with the surface. In operation, the rotating drum begins its rotation while the roller and blade are in their inoperative position. The drum surface contacts liquid developer solution at the developing station. The roller and blade contact the drum after a predetermined time duration and therefore contact a wetted drum surface so as to avoid possible damage to the photosensitive surface and the cleaning members. A delay arrangement directs developer to the cleaning blade and roller when they are in their operative position contacting the drum.
