A fixing member including: a substantially cylindrical support and one or more layers provided on or above the support, including a surface layer that constitutes the outermost surface, the fixing member having: a difference in the width direction of the support between the maximum value and minimum value of the total thickness of the support together with all the layers provided on or above the support being approximately 50 mum or less; the surface layer consisting of a seamless member comprising a fluorine-containing solid material, the composition of the fluorine-containing solid material varying in the width direction of the support; the average thickness of the surface layer being in the range of approximately 20 mum to approximately 50 mum; a difference in the width direction of the support between the maximum value and minimum value of the thickness of the surface layer being approximately 5 mum or less; and the dynamic friction coefficient on the surface of the surface layer at 120° C. varying in the width direction of the support.
