  • Patent number: 3996888
    Abstract: An apparatus for lubricating and/or cleaning a heated fuser roller in a heat-pressure fusing system for electrophotographic copying. The apparatus includes a lubricating and/or cleaning means in contact with the heated fuser roll, the means including a cross-linked polymeric material on its outer surface. The polymeric material may have a leachable lubricating material dispersed therein, for controlled lubrication of the fuser roller. After depletion of the lubricating material, the cross-linked polymeric material then functions to remove and collect the toner particles from the surface of the toner fuser roller. The apparatus is preferably mounted in contact with the fuser roller by a means which permits easy removal and replacement in the field, after the lubricant has been depleted or the polymeric material has become saturated with toner particles.
