SEAMLESS TUBULAR ARTICLE, ITS MANUFACTURING METHOD, AND IMAGE FORMING APPARATUS USING OBTAINED SEAMLESS TUBULAR ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for inexpensively manufacturing a seamless tubular article having a high product yield and the seamless tubular article having a high accuracy obtained by the method and to provide an image forming apparatus using the obtained seamless tubular article.;SOLUTION: The method for manufacturing the seamless tubular article made of a heat resistant resin composition comprises a coating step of coating the surface of a core made of a metal covered with a coating layer made of an organoalkoxide layer with a liquid-like heat resistant resin composition, a solidifying step of solidifying or curing the liquid-like heat resistant resin composition coating on the surface of the core, and a separating step of separating the solidified or cured heat resistant resin composition from the core. The seamless tubular article is obtained by the method. The image forming apparatus uses the seamless tubular article.;COPYRIGHT: (C)2003,JPO
