摘要:
In an electrophotographic endless belt having a resin layer formed of a resin composition containing a polyamide, the resin composition further contains a copolymer obtained by copolymerization of an olefin and an oxygen-containing heterocyclic compound, a curve (T−log10η curve) showing the relationship between temperature T (° C.) and common logarithm log10η of melt viscosity η (Pa·s), of the resin composition has, in the range of log10η of from log10 1,000 to log10 8,000, a gently inclined region the inclination Δlog10η/ΔT of which is from −0.02 to 0, and the gently inclined region has a temperature range of 10° C. or more, and the resin layer has a thickness the maximum thickness of which is 115% or less of the average value of the thickness of the resin layer and the minimum thickness of which is 85% or more of the average value of the thickness of the resin layer. Also disclosed is a process for producing the above electrophotographic endless belt.
