Conveying roller for photosensitive material and method of producing the same

摘要

Continuous photo film (11) includes a support (11a) of resin film having a back surface. A photosensitive layer (11b) 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 (31) of metal. A hardness reinforcer layer (32) is formed on a surface of the roller body by thermal spraying and from ceramic or cermet, and avoids being scratched or ground by the back surface.
