Roll fuser apparatus and cleaning structure therefor. The cleaning structure is characterized by the provision of a pad supported in rubbing contact with the backup roll of the roll fuser apparatus. The pad is constructed so that approximately 75% of its total volume is made of intercommunicated voids so that toner removed from the backup roll can move freely therethrough and not agglomerate at the surface of the pad as in the case of prior art devices. In one embodiment of the invention the back surface of the pad is unobstructed to allow toner to actually move out of the pad thereby increasing the useful cleaning life of the pad. |
