Abstract:
An apparatus for manufacturing a heater roller which includes a cylindrical electrically insulating substrate having a circumferential surface, and an electrically resistive heat generating layer which is formed on the circumferential surface of said substrate, for heating a desired member in evenly pressing contact with said desired member, said apparatus comprising:a rotating device for holding said cylindrical electrically insulating substrate rotatably about an axis thereof, and rotating said cylindrical electrically insulating substrate about said axis;a paste delivery device having a paste delivery tube, for delivering an electrically resistive paste for forming said electrically resistive layer, from said paste delivery tube onto said circumferential surface of said cylindrical electrically insulating substrate, said paste delivery tube having bending elasticity;an axial drive device for moving said paste delivery device and said cylindrical electrically insulating substrate relative to each other in an axial direction of said cylindrical electrically insulating substrate;a relative position detecting device for detecting a relative position of said paste delivery device and said cylindrical electrically insulating substrate, on the basis of said relative position detected by said relative position detecting device;a control device for controlling a speed of a relative movement of said paste delivery device and said cylindrical electrically insulating substrate, on the basis of said relative position detected by said relative position detecting device; anda pushing device for holding an end portion of said paste delivery tube in pressing contact with said circumferential surface of said cylindrical electrically insulating substrate, such that said end portion is inclined at a predetermined angle with respect to a line tangent to a circumference of said circumferential surface.
