PROBLEM TO BE SOLVED: To obtain a polyimide tubular molding which is useful in an electrophotographic apparatus such as a laser beam printer, a facsimile, etc., and has a greatly improved life. SOLUTION: The polyimide tubular molding is a cylindrical molding containing a polyimide resin and has 60-100μm thickness and≥5.0×10<SP>3</SP>times of flexing resistance by MIT test defined by JIS P8115. The electrophotographic apparatus causes no damage by crack initiation even after driving for many hours and stably provides an excellent image and thereby, the running cost of the electrophotographic apparatus is dramatically reduced by the polyimide tubular molding.
