Claim:
1. A fixing member comprising: a surface layer containing polytetrafluoroethylene (PTFE) and a fluorine resin having a melting point lower than that of the PTFE, wherein, in a DSC (endothermic) curve obtained by heating a sample of the surface layer at a temperature raising rate of 20° C./min with a differential scanning calorimeter (DSC), an endothermic peak 1 having a peak top in a temperature range of 330° C. to 340° C. and an endothermic peak 2 having a peak top in a temperature range lower than that of the endothermic peak 1 are present, and wherein a sum ΔH of an amount of heat of fusion based on the endothermic peak 1 and an amount of heat of fusion based on the endothermic peak 2 is 40 J/g to 55 J/g.
