Abstract (en)

In a seamless film belt comprising a lamination of at least two layers, a modulus of elasticity of the outermost layer is established to be larger than that of the innermost layer. With this constitution, the seamless film belt which scarcely expands and scarcely develops cracks can be provided. When this is used in an electrophotography apparatus as an intermediate transfer belt, a high precision and uniform image can be obtained stably for a long period of time. <IMAGE>
