Abstract
The invention relates to a technique which enables good electric contact to be surely made between a heat roller and conducting terminals serving as feed means. The heat roller comprises a heating portion and shaft portions which are integrally molded from the same material in the form of a molded member at least both end portions of which are hollow. The conducting terminals are capable of elastically expanding and contracting in the radial direction and are closely fitted into the hollow portions at both ends of the molded member.
