摘要： A fixing member having the form of a film or belt which is multi-layer constructed to have at least a base layer and a surface layer. The base layer is formed of a material having radiation-transmitting properties, capable of transmitting radiation coming from a radiation source disposed on the back side of the base layer in non-contact with the fixing member. Also disclosed is a fixing assembly having this fixing member and a radiation source disposed on the internal side of the fixing member. Even though the radiation source is disposed on the internal side of the fixing member, the fixing member can perform good surface heating in a good heat response.
