ABSTRACT:
Method and apparatus for manufacturing a heater roller which includes a cylindrical electrically insulating substrate having an outer circumferential surface, and an electrically resistive heat generating layer formed on the substrate for heating a desired member in evenly pressing contact with that member, wherein an electrically resistive paste for forming the electrically resistive layer is delivered from a paste delivery tube of a paste delivery device onto the outer circumferential surface of the substrate, while the cylindrical substrate is rotated about its axis and while the paste delivery device and the electrically insulating substrate are fed relative to each other in the axial direction of the cylindrical substrate, such that the relative feeding speed is controlled in relation to the relative position of the paste delivery device and the substrate in the axial direction of the substrate, within a range that permits formation of a film of the electrically resistive paste on the substrate, which film is continuous in the axial direction of the substrate.
