Abstract

A cleaning system is used in an electrophoto aphic printing machine to transfer of the developed image to the copy sheet. In order to prevent contamination of the various subsystems within the printing machine by the residual developer material, it is necessary to prevent the escape of the developer material from the housing of the cleaning system. A detoning roll, in the cleaning housing, electrostatically attracts the developer material from the photoconductive member. The seal contacts the surface of the detoning roll having the residual developer material electrostatically attracted thereto with a low force. In this way, the electrostatically attached material is not disturbed by the seal while sealing against the escape of airborne developer material from the housing.
