Abstract:
A fixing device comprising:an endless heating member which is adapted to be contacted with a fixable member to thereby enable an image on the fixable member to be thermally fixed; an electromagnetic inductive coil member disposed close to the endless heating member and inductively heating the endless heating member; and an AC power supply circuit supplying an AC current to said coil member, wherein said coil member is constructed such that in a state where said coil member is positioned in the fixing device, a ratio between an inductance L of said coil member and a load resistance R of said coil member meets a condition of: L/R<50Ã—10âˆ’6 (H/&OHgr;), and wherein said coil member comprises a non-magnetic coil-supporting member, and a coil supported by said non-magnetic coil-supporting member.
