PROBLEM TO BE SOLVED: To obtain heating equipment of an induction heating, fixing equipment, and image forming equipment, in which a magnetic flux generating coil does not become high temperature, and a body of revolution can be uniformly heated in its length direction and also can be almost uniformly heated in its circumference direction of the body of revolution. SOLUTION: The heating equipment constitutes of the body of revolution 11 having an induction heating body, a pressurizing component 13, which is cramped with pressure to the body of revolution 11, and a magnetic flux generating means 12 arranged facing the perimeter of the body of revolution 11, and heats up the heated body by making the heated body pass through between the body of revolution and the pressurizing component 13. The magnetic flux generating means 12 has a core 21, which consists of a high magnetic permeability material, and a conductive wire rod 30, which is wound on the core 21 in parallel in the length direction of the body of revolution 11, and supplies frequency current. The core 21 approaches the body of revolution 11 to the closest distance in the both-sides end of the core 21 or its near in a direction perpendicular to a plane made by a torus, which the conductive wire rod 30 makes. The distance of the core 21 and the body of revolution 11 in the closest approaching position is constant in the longer direction of the body of revolution 11, and the conductive wire rod 30 is wound around the core 21 avoiding the above closest approach position.
