A self-lubricating residual toner cleaning apparatus is provided and includes (i) a cleaning blade member for removing charged loosened residual toner particles having a first polarity from a toner image bearing surface at a first point; (ii) a disturber fiber brush, mounted at a second point for loosening residual particles from the surface; (iii) a reversible bias source connected to the disturber fiber brush for normally biasing the disturber fiber brush to a second polarity to attract the residual toner particles; and (iv) a controller connected to the reversible bias source for periodically reversing the normally biasing polarity from the second polarity to the first polarity momentarily repelling loosened residual toner particles from the disturber fiber brush back onto the surface, thereby providing a relatively increased amount of residual toner particles on a portion of the surface for contacting and lubricating the cleaning blade member.
