摘要：
A process for producing an endless belt includes melt-extruding an extrusion material into a cylinder by means of an extruder, where the extrusion material has a tensile break strength of 400 kgf/cm2 or above and a breaking extension of from 3.0% to 250%, and where the extrusion material is extruded in an extrusion ratio of from 1.05 to 2.80 while a gas is blown into the inside of the melt-extruded cylindrical product.
