Abstract
An electrophotographic fixing member having an elastic layer that is high in thermal conductivity in the thickness direction, resists causing fracture or plastic deformation even by repeated compression in a high temperature state, and is low in hardness. The electrophotographic fixing member has a substrate, and an elastic layer provided on the substrate, wherein the elastic layer contains a filler containing an inorganic oxide and is provided on an outer circumference of the substrate, wherein (1) in a binarized image on a first cross-section in a thickness-circumferential direction of the elastic layer and a binarized image on a second cross-section in a thickness-axial direction of the elastic layer, 1.0≤(A/B)≤2.0 and 0.40≤(A+B)≤0.50 are satisfied; and (2) 50°≤θ≤90° is satisfied.
