Abstract
The present invention provides a fixing apparatus which can secure a sufficient fixing performance even if a nip pressure is arranged in relatively low value. A fixing apparatus comprises a fixing member (,) having an elastic layer (,B,,B) formed on the fixing member at a side to which a sheet surface supporting an unfixed toner is contacted; a pressing member (,) for making the sheet surface supporting the unfixed toner contact to the fixing member (,) with a particular pressure and forming a nip portion between the fixing member and the pressing member; and a heating means (,) heating the fixing member(,), wherein 0.05≦P·t/E≦0.50 is satisfied, where t (mm) is thickness of the elastic layer (,B,,B), E (Pa) is Young's modulus of the elastic layer (,B,,B) and P (Pa) is pressure in the nip portion.
