Abstract

PURPOSE: To cut down the waiting time until operation by facilitating the standardization of parts with heat rollers made by providing a heat source on a cylinder made by assembling the heat pipe of heat fixing apparatuses for electronic photoduplicators for example.
CONSTITUTION: Several independent pieces of heat pipe 7 are arranged to the inside of the external cylinder 6 parallel to the rotational axis of, the external cylinder so as to contact with the inner circumference of, the external cylinder 6, and a coating layer of silicon rubber etc. is formed on the outer side face of the cylinder 6. The heat of a heater 9 supported on an end plate 8 is transmitted to the heat pipe 7, cylinder 6 and coating layer. Since the feat pipe 7 and cylinder 6 are thus separated, standardization can be made for size change etc., repair can be made by replacing the pipe 7, the efficiency of heat transmission orthogonal to the axis of heat rollers is raised so that the waiting time until operation can be cut down.
