ABSTRACT:
Continuous photo film includes a support of resin film having a back surface. A photosensitive layer of photographic emulsion is disposed on a surface of the support opposite to the back surface. A conveying roller conveys the continuous photo film. The conveying roller includes a roller body of metal. A hardness reinforcer layer is formed on a surface of the roller body by thermal spraying of ceramic or cermet, so that the roller body surface is prevented from being scratched or ground by the back surface of the film.
