Automatic processing machine and method for manufacturing conveying rollers used therein

An automatic processing machine in which an exposed photographic photosensitive material is subjected to development processing, comprising:

• a processing-solution processing section in which the photographic photosensitive material is subjected to development processing in such a manner as to be sequentially immersed in a developing solution filled in a developing tank, a fixing solution filled in a fixing tank, and washing water filled in a washing tank;
• a drying section in which the photographic photosensitive material processed in said processing-solution processing section is subjected to drying processing;
• and
• at least one conveying roller pair which is disposed at any one of a crossover portion between the developing tank and the fixing tank, and a position between the washing tank and said drying section,
• wherein one of said conveying roller pair includes a peripheral surface of silicone rubber, manufactured by conducting primary cross-linking for one hour and secondary cross-linking for 6 hours or more, preferably 10 hours or more using silicon as a cross-linking material.

• a drying section in which the photographic photosensitive material processed in said processing-solution is subjected to drying processing;
• and
• at least one means for nipping and guiding the photosensitive material, disposed unsubmerged at any one of a crossover portion between the developing tank and the fixing tank, and between the washing tank and the drying section,
• wherein a contact angle of a water drop on a surface of the nipping and guiding means in contact with a photographic emulsion surface of the photographic photosensitive surface is less than 135°.
