An image heating member includes a first region having a Curie temperature higher than a preset temperature, and a second region having a Curie temperature lower than the Curie temperature of the first region. A width of the first region in a conveying direction of a recording material is equal to or larger than a width of the recording material of a maximum size to be fed. The second region is provided outside the first region.

In order to prevent non-sheet passing portion temperature rise occurred in a non-sheet passing area of an electromagnetic induction heating member, leakage of magnetic flux is reduced by setting a Curie temperature of the heating memberto be smaller than an acceptable upper limit temperature and setting a thickness of the heating member so that a thickness tk in a Curie temperature arrival area (P&#x2212;P) is larger than a thickness tn in a Curie temperature non-arrival area Pwhich is a conveyance area of a material to be heated having a minimum passing size.

Induction image heating apparatus

A filler for separating an optical isomer comprising a surface-hydrophobic filler component and an optically active lipophilic crown compound carried on the filler component by adsorption. The filler may be charged in a column to carry out separation of a sample such as amino acid or the like in the form of an aqueous solution.
