Abstract:
An image heating apparatus comprising:a rotary member;a coil for generating a magnetic flux;a first magnetic portion and a second magnetic portion for guiding the magnetic flux generated by said coil; andwherein an end of said first magnetic portion is disposed opposite to an end of said second magnetic portion with a gap, and the magnetic flux is guided by said first magnetic portion and said second magnetic portion via said rotary member, andwherein the magnetic flux generates an eddy current in said rotary member, and said rotary member generates heat by the eddy current,a roller for forming a nip with said rotary member;wherein a recording material bearing an image is pinched and conveyed by said nip, and the image is heated by a heat of said rotary member, andwherein the end of said first magnetic portion and the end of said second magnetic portion are present within a width along a recording material moving direction of said nip, and a width of said gap along the recording material moving direction is different with respect to a direction which is orthogonal to the recording material moving direction.
