Patent ID: 7201967

Claim:
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-log 10 η curve) showing the relationship between temperature T (° C.) and common logarithm log 10 η of melt viscosity η (Pa·s), of said resin composition has, in the range of log 10 η of from log 10 1,000 to log 10 8,000, a gently inclined region the inclination Δ log 10 η/ΔT 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.
