Device simultaneously cleaning electrostatographic fixing and auxiliary heating rollers

摘要

Auxiliary heating roller(s) employed in an electrostatographic fixing station are cleaned at low cost by the efficient use of the reverse side of a disposable cleaning web which conventionally has been discarded after using its one side alone. Cleaning web devices 15 and 16 are installed in top and bottom ends of a fixing station, wherein auxiliary heating rollers 5 and 6 ride respectively on a heating roller 3 and a pressure roller 4 of a fixing roller pair. The cleaning web devices 15 and 16 are configured therein to clean the fixing rollers initially, employing an obverse side A of a cleaning web 21 in the respective devices, which winds around turnaround rollers such that thereafter the reverse side B of the cleaning web 21 is employed to clean the surfaces of the auxiliary heating rollers 5 and 6.
