PROBLEM TO BE SOLVED: To obtain the image forming device of a resin intermediate transfer belt system by which excellent image quality is obtained and whose life is prolonged and whose maintainability is improved by setting a belt-like intermediate transfer body as a seamless belt. SOLUTION: An electrostatic latent image on a latent image carrier is developed as a visible image, and after it is transferred to an intermediate transfer body, it is transferred to a transfer material again in this image forming device. In this case, a device possesses an intermediate transfer unit provided with a mechanism to always lay the belt-like intermediate transfer body of thin film between plural axes by the tension of 100 kg/cm2-1000 g/cm2 and to apply an electric field while directly coming into contact with the intermediate transfer body, and also the belt-like intermediate transfer body is set to be the seamless belt continuously molded with thermoplastic resin whose stress is 2 kgf/mm2-8 kgf/mm2 when it is elongated by 2% and whose thickness is 30μm-300μm.
