ABSTRACT:
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.
