Abstract

A system for removal of toner particles from a transfer support member surface without the necessity of an independent toner recovery system. A cleaning blade on the transfer support member collects and accumulates residual toner particles. When a non-image area on the photoconductor passes beneath the blade, the blade is spaced from the photoconductor and a reverse bias applied to the transfer support member so that the accumulated particles are transferred to the photoconductive surface. Subsequently, the cleaning system associated with the photoconductive member removes these toner particles.
