Abstract
A heating roller device which incorporates a metal roller having a curier temperature adjusted to an appropriate level and enabling a self-temperature-controllability and which has a structure that the metal roller is induction-heated by an induction heating section. A method of manufacturing the foregoing metal roller according to the present invention has a step of joining a pipe, which is made of temperature-sensitive magnetic metal, and the composition of which has been adjusted so as to have a predetermined curier temperature, and metal having a resistivity lower than that of the temperature-sensitive magnetic metal to each other by a drawing work in such a manner as to prevent formation of any gap. Thus, an induction heating pipe exhibiting an excellent heating characteristic is manufactured.
