Abstract

A thermal fixing device which includes a heat roller which is positioned to contact a toner image-bearing surface of a copy sheet in order to completely fix the already preliminarily fixed toner image as the copy sheet moves through the thermal fixing device, the surface of the heat roller being made of RTV silicone rubber which contains 25 to 35% by weight of non-reactive dimethyl silicone oil having a viscosity of 10 to 300 centistoke and a trimethyl siloxy group as an end group. The heat roller contacts the toner image-bearing surface of the copy sheet with a total pressure of about 1.5 to 4.5Kg.
