Abstract
Heat and pressure fusing apparatus for fixing toner images. The fusing apparatus is characterized by the separation of the heat and pressure functions such that the heat and pressure are effected at different locations on a thin flexible belt forming the toner contacting surface. A pressure roll cooperates with a stationary mandrel to form a nip through which the belt and copy substrate pass simultaneously. The belt is heated such that by the time it passes through the nip its temperature together with the applied pressure is sufficient for fusing the toner images passing therethrough. A release agent management (RAM) system comprising low mass donor and metering rolls, one of which is in contact with the belt, applies silicon oil to the belt without unacceptably reducing the fusing capability of the belt.
