Abstract

The present invention is characterized in that, for the purpose of achieving a heating member (fixing member) in which thermal conductivity or electrical conductivity is given to a resin surface layer without loss of releasability, and heating efficiently is improved, the heating member contacting a to-be-heated member and heating the same has a surface layer 15 in which, in a resin material 43 having releasability, a material (for example, metal) 44 having either one or both thermal conductivity and electrical conductivity is mixed, and the material contact successively. Specifically, the heating member (fixing member) according to the present invention has the surface layer 15 in which the metal 44 is mixed into the fluorocarbon resin 43, and the metal 44 forms metal successively contacting part 42 in which the metal 44 successively contacts in such a manner as to surround the fluorocarbon resin part 41. Thereby, it is possible to improve thermal conductivity or electrical conductivity while maintaining releasability.
