Abstract

PURPOSE: To simplify the constitution of a heat pipe roller of a thermal fixing device for the copier and facilitate its assembly by constituting a welded construction in which an outer cylindrical pipe into which a thermal medium of less than one atmospheric pressure is sealed is welded to an inner cylindrical pipe integral with a shaft provided with a heating member.
