Abstract:
A fixing member for electrophotography having an endless shape has a base layer having an endless shape, and an elastic layer on the outer circumferential surface of the base layer. The elastic layer includes a silicone rubber and a filler dispersed in the silicone rubber. The total amount of the filler compounded in the elastic layer is 30 vol % or less based on the total volume of the elastic layer. The elastic layer satisfies the relation of λtd>λmd>λnd. λtd is a thermal conductivity of the elastic layer in the circumferential direction, λnd is a thermal conductivity of the elastic layer in the thickness direction, and λmd, is a thermal conductivity of the elastic layer in the longitudinal direction. λtd is 2.0 W/(m·K) or more, and λnd is 1.3 W/(m·K) or more.
