Patent ID: 8913934

Claim:
A cold pressure fusing apparatus for use in a xerographic copying machine for fixing a developed toner image to a copy sheet, comprising: a photoconductor mounted in said machine; a driving means operatively connected to said photoconductor, the photoconductor supporting developed toner images, the photoconductor being warmed to a temperature above room temperature, a pressure roll mounted in said machine, the pressure roll in pressure contact with the photoconductor, the pressure roll and photoconductor forming a nip, a pressure at the nip being low, and the temperature of at least one of the pressure roll and photoconductor being high with respect to the other, copy sheets entering the nip to receive a developed toner image from the photoconductor, the copy sheets exiting the nip with the developed toner image fixed to the copy sheet, and the pressure roll providing suitable pressure in relationship to the toner material to fix the developed toner image to the copy sheet, wherein the suitable pressure to fix the toner image on the copy sheet is in relationship to temperature.
