Patent ID: 7660554

Claim:
A heat fixing device comprising: a heating target member that is endless, has a metal conductive layer supported by an elastic member and has a first length in an axial direction; a pressure member that has a second length extending to outsides of both sides of the heating target member in the axial direction and having a hardness larger than a hardness of the heating target member, comes in press contact with the heating target member at a side opposite to the elastic member, and, together with the heating target member, nips and carries a fixing target medium in a specified direction; an induction current generation member that is disposed at a periphery of the heating target member and heats the metal conductive layer; and a regulating member to regulate both sides of the heating target member in an axial direction and to prevent the heating target member from moving in the axial direction, and the regulating member is a regulating wall provided at both sides of the induction current generation member in a longitudinal direction.
