Manufacture of thermal fixing roller

Abstract

PURPOSE:To manufacture a thermal fixing roller capable of obtaining high picture quality, excellent durability, high quality and high performance stably at low cost. CONSTITUTION:A rubber layer is formed onto a metallic center core, the surface of the rubber layer is coated with a fluororesin, the rubber layer is irradiated with near infrared rays from a section near the surface of the rubber layer and the surface temperature of a fluororesin coating is elevated up to 360-400 deg.C, and the temperature is held for a time T (sec) satisfying the following formula, and the fluororesin coating is baked; 0.03W<=T<=0.1W (in the formula, W represents the weight (g) of a roller after coated with the fluororesin).
