1. An electrophotographic endless belt comprising a resin layer formed of a resin composition containing a polyamide, wherein;

  • said resin composition further contains a copolymer obtained by copolymerization of an olefin and an oxygen-containing heterocyclic compound;

    a curve (T-log10 η

    curve) showing the relationship between temperature T (°

    C.) and common logarithm log10 η

    of melt viscosity η

    (Pa·

    s), of said resin composition has, in the range of log10 η

    of from log10 1,000 to log10 8,000, a gently inclined region the inclination Δ

    log10 η



    T of which is from −

    0.02 to 0, and the gently inclined region has a temperature range of 10°

    C. or more; and

    said resin layer has a thickness the maximum thickness of which is 115% or less of the average value of the thickness of said resin layer and the minimum thickness of which is 85% or more of the average value of the thickness of said resin layer.
