Abstract: A method of manufacturing a tubular film includes the steps of: winding a thermoplastic sheet film on a columnar member with at least two turns so that leading and trailing ends of the film are placed approximately on one normal line of an outer surface of the columnar member without overlapping each other; fitting a tubular molding member on the wound film; and connecting the leading and trailing ends of the film by heating at least the film, thereby forming the sheet film into the tubular film. The resulting tubular film has a high film thickness uniformity and suitable for a fixing film of an image forming apparatus.
