ABSTRACT:
A fixing method for a wet process copier which develops an electrostatic latent image by using a heat-bridging type toner, transfers the resulting toner image to a paper sheet, and fixes the toner image transferred on the paper sheet by transporting the paper sheet through a nipping section defined by a heating roller and a pressing roller such that the side of the paper sheet carrying the toner image directly contacts the heating roller. At least a surface portion of the heating roller is made of either one of monomeric, additive-free RTV (Room Temperature Vulcanized) and LTV (Low Temperature Vulcanized) silicone rubbers. The heating roller has average surface roughness of less than 3 microns.
