摘要:
A heat fixing roll for a copying machine includes an insulating layer formed on the surface of a hollow tube, a heating resistor layer formed on the surface of the insulating layer by uniformly thermal spray coating a resistor material, a screw-like heating resistor formed by forming a helical groove having a depth reaching the surface of the insulating layer by using a laser irradiation head connected to an electric resistance compensator, and an antisticking layer formed on the surface of the resistor and the groove by coating. The present invention also provides a method of producing the heat fixing roll and an electronic copying machine provided with the roll.
