Description of the Invention: [Technical Field of the Invention] The present invention relates to a seamle belt used for an electronic device, a conveyor, or the like, and a method of manufacturing the same. [Prior Art] As a general matter, (four) is very expensive, and it is used as a main component in place of a gear in an industry that uses a rotating shaft and an electric motor such as an electronic device or a steam core conveyor. In particular, in electronic equipment, 'used in photocopiers or laser printers, fax machines, etc., also for fixing and transferring toner images formed on copy paper or transfer paper, used as fixing belt or intermediate Transfer belt, conveyor belt. Timing belts and conveyor belts used in automobiles are also familiar to ordinary people. Since the belt is likely to generate static electricity during the rotation, an antistatic function is required. In order to resist the semiconductivity of the electrostatic function, it is also applied to the physical properties for toner transfer in electronic equipment. 70 Such belts are based on the tube type and range from small belts with a diameter of 2 mm to a few meters with a few meters. However, most of the belts are belts having seams connecting flat belts or V belts, and the belts have irregularities at the joint portions. There is a problem that the surface characteristics of the joint portions are different from those of the surroundings. Special '=Yes> The unevenness of the surface of the belt of the intermediate transfer belt using the uniform flat electronic device of the belt, the special color laser printer is damaged by the drum, or the quality of the printed image is lowered. Further, in the case of seam-point-point twisting, the linearity of the tubular belt is impaired, and the rotation t also becomes a cause of skewing. In the case where the oblique line of the belt causes the belt to be detached from the driving roller, there is a possibility that the device itself is damaged. Therefore, 'If there is no seam on the tubular belt, the maximum that is transmitted to the belt (4) = because there is no unevenness, it can prevent the phenomenon of the belt in the rotation or the object in contact with the belt, which can easily ensure the belt Straightness. Miscellaneous special use as a printer, photocopier, multifunction machine, fax machine, etc. The fixing belt and intermediate transfer belt of the belt need to have pollution, heat resistance, heat dissipation characteristics, elastic modulus, and power removal.
