Abstract (en)

[origin: WO9807075A1] A seamless belt has a layer-built structure of at least two layers. The elasticity of the outer layer of the seamless belt is larger than the elasticity of the inner layer. With this constitution, the seamless belt which is difficult to expand and difficult to develop crackings is provided. When the seamless belt 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.
