고품위의 전자 사진용 엔드리스 벨트 및 그 벨트를 효율적으로 제조할 수 있는 방법의 제공. 열가소성 수지 조성물을 포함하는 기층과 내표면층을 갖고 있는 전자 사진용 엔드리스 벨트의 제조 방법으로서, (1) 열가소성 수지를 포함하는, 시험관 형상의 프리폼의 내표면에 유리 전이 온도를 갖는 에너지 경화성 피막을 형성하고, 계속해서, 그 프리폼을 블로우 성형하여 블로우 보틀을 얻는 공정과, (2) 그 블로우 보틀에 에너지선을 조사하여 상기 피막을 경화시켜서 내표면층을 형성하는 공정과, (3) 공정 (2)에 의해 얻은 내표면층을 갖는 블로우 보틀로부터 엔드리스 벨트를 잘라내는 공정을 갖는다. A high-quality electrophotographic endless belt and a method capable of efficiently producing the belt are provided. A method for producing an electrophotographic endless belt comprising a base layer including a thermoplastic resin composition and an inner-surface layer, which includes: (1) forming an energy curable film having a glass transition temperature on an inner surface of a test tube-shaped preform including a thermoplastic resin and then subjecting the preform to blow molding to obtain a blow-molded bottle; (2) irradiating the blow-molded bottle with energy rays to cure the film to form an inner-surface layer; and (3) cutting out an endless belt from the blow-molded bottle having the inner-surface layer obtained in (2).
