Abstract:
1. An image heating apparatus comprising: an exciting coil; a current applying device configured to apply a high-frequency current to said exciting coil; a rotatable heating member configured to heat a toner image on a recording material at a nip, said rotatable heating member including an electroconductive base layer for generating heat by electromagnetic induction of magnetic flux from said exciting coil and an insulating surface layer provided on the electroconductive base layer; a rotatable pressing member configured to press-contact said rotatable heating member to form the nip, said rotatable pressing member including an electroconductive surface layer having (i) a volume resistivity of 10 a rectifying element configured to be connected between the electroconductive surface layer and the ground in a direction in which a surface potential of said rotatable pressing member has an opposite polarity to a normal charge polarity of a toner.
