Tapered donor roll applicator for roll fuser |
摘要 |
A heat and pressure roll fusing apparatus for fixing toner images to copy substrates, the toner comprising a thermoplastic resin. The apparatus includes a heated, either internally or externally, fuser roll cooperating with a backup or pressure roll to form a nip through which the copy substrates pass with the images contacting the heated roll. The heated fuser roll is characterized by an outer layer or surface fabricated from a silicone rubber material to which a low viscosity polymeric release fluid is applied, the silicone rubber being susceptible to swelling in the presence of the release fluid. A release fluid metering system is provided which includes a tapered roll that is adapted to apply release fluid to the entire outer fuser roll surface or to only a portion thereof depending upon the size substrate being utilized.
