Abstract
A pressure roll for use in a roll fuser for fixing toner images to copy sheets by the application of heat and pressure, is described. The roll is characterized by a rigid core covered with a relatively thick layer of organic rubber with a relatively thinner sleeve or layer of material acting as an air barrier to the organic rubber to prevent oxidative degradation. The organic rubbers are characterized by small compression deflection decreases even after exposure to high temperatures, under pressure for prolonged periods of time.
