Patent ID: 8150306

Claim:
A fixing device comprising: a first rotate-heat-generating member comprising a metal layer which is to be induction-heated; a first induction current generating device arranged in proximity to the first rotate-heat-generating member; a second rotate-heat-generating member comprising a second metal layer which is to be induction-heated, the second rotate-heat-generating member forms a nip with the first rotate-heat-generating member; and a second induction current generating device which is arranged on the periphery of the second rotate-heat-generating member, and is divided into plural coils in an axial direction, and the second induction current generating device heats the second rotate-heat-generating member by induction heating, and the second induction current generating device is arranged at a location a first distance that an outer periphery of the first rotate-heat-generating member moves from a center of induction heating by the first induction current generating device to the nip is equal to a second distance that an outer periphery of the second induction current generating device moves from a center of induction heating of the second induction current generating device to the nip.
