Heating member and heat fixing apparatus using the same

A heating member usable with a heater, said heating member comprising:

• an insulating protective layer disposed on the surface of the heater;
• a separation-preventive layer disposed on said insulating protective layer;
• and
• a lubricating and protective layer disposed on said separation-preventive layer, said lubricating and protective layer comprising a vapor deposited layer that is made of carbon or the main component of which is carbon,
• said separation-preventive layer being provided to impede separation of said lubricating and protective layer from the heater,
• wherein said separation-preventive layer comprises a substance selected from the group consisting of:
• (a) Si;
• (b) B;
• (c) elements Ti, Zr, and Hf of group IVB of the periodic table;
• (d) elements V, Nb, and Ta of group VB of the periodic table;
• (e) elements Cr, Mo, and W of group VIB of the periodic table;
• (f) an oxide, a carbide, a nitride, a carbon nitride, a carbon oxide, and a carbonate nitride of any of said elements (a)-(e);
• (g) a boride and a boron nitride of any of said elements (a) and (c)-(e);
• and
• a compound of at least two types of said elements (a)-(e),
• wherein said separation-preventive layer comprises a vapor deposited layer, and a concentration of hydrogen contained in the vapor deposited layer of said separation-preventive layer is higher than a concentration of hydrogen contained in said lubricating and protective layer.
