TUBULAR RESIN MOLDING AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyimide molding which greatly improves the life of a tubular resin molding used for an electrophotographic device, such as a laser beam printer or a facsimile. SOLUTION: The tubular resin molding which is a tubular resin molding provided with a base material and position detecting marks varying in reflectivity and is previously provided with the position detecting marks in areas of a small thickness previously disposed on the tubular resin molding and the method of manufacturing the same. The tubular resin molding which is extremely little in cracking to the tubular resin molding or peeling and removing of the position detecting marks and deposition of toners arising in level difference sections can be provided. The life of the tubular resin molding which is a consumable of the electrophotographic device is therefore greatly improved and eventually the running cost of the electrophotographic device can be drastically reduced.
