To provide an endless belt excellent in flexibility, chemical resistance and molding dimensional stability and restraining material deterioration due to reaction at the melting and mixing time, and to provide a belt for an image forming device using the endless belt, and an image forming device using the belt for an image forming device.
As to this endless belt, the flexibility by JIS P-8115 in the circumferential direction of the belt exceeds 5000 times, tensile elastic modulus in the circumferential direction of the belt is 1500 to 5000 Mpa, tensile rupture elongation in both directions, such as the circumferential direction and the width direction of the belt is ≥30%, the average thickness of the belt is 70 to 300 μm, the surface electric resistivity is 1×101 to 1×1016 Ω or volume electric resistivity is 1×101 to 1×1016 Ω.cm, and the maximum value of the resistivity of one endless belt is set to 100 or less times as large as the minimum value thereof. Then, the belt for the image forming device using the endless belt, and the image forming device using the belt for the image forming device are provided.
