An image heating apparatus for heating an image formed on a recording material includes: a cylindrical rotatable member including a base layer and an electroconductive layer; a core inserted into the rotatable member; and a coil wound helically around the core inside the rotatable member, wherein an AC magnetic field is formed by passing an AC current through the coil to generate heat in the electroconductive layer through electromagnetic induction heating. The base layer has a volume resistivity higher than a volume resistivity of the base layer. The electroconductive layer generates heat through a full circumference thereof by a current flowing in a circumferential direction of the rotatable member independently of rotation of the rotatable member.
