Photosensitive material turning member and developing apparatus

A photosensitive material turning member provided in a tank that stores processing solution to which a band-shaped photosensitive material having a silver salt containing layer on a base film is conveyed, the photosensitive material turning member allowing the band-shaped photosensitive material to float with respect to the photosensitive material turning member such that the band-shaped photosensitive material is turned without contacting the photosensitive material turning member, the photosensitive material turning member comprising:

• a first cylindrical member disposed in a direction crossing a conveying direction of the band-shaped photosensitive material that has, on a surface thereof in a longitudinal direction, a plurality of slit-shaped discharge openings that discharge the processing solution;
• and
• a second cylindrical member disposed inside the first cylindrical member that has nozzles that eject the processing solution,
• wherein the discharge openings are formed in a tapered shape, which are wider on a front surface side of the first cylindrical member and narrower on a rear surface side of the first cylindrical member.

• and
• a second cylindrical member disposed inside the first cylindrical member that has nozzles that eject the processing solution,
• wherein the second cylindrical member is provided with an introduction portion that introduces the processing solution at one longitudinal end of the second cylindrical member, and
• the nozzles are a plurality of nozzle holes formed in the longitudinal direction,
• the nozzle holes formed at the other longitudinal end are smaller than the nozzle holes formed at the one longitudinal end, and
• the nozzle holes become gradually larger from the other longitudinal end to the one longitudinal end of the second cylindrical member.

• and
• a second cylindrical member disposed inside the first cylindrical member that has nozzles that eject the processing solution,
• wherein the first cylindrical member has no discharge opening at a portion that faces the nozzles of the second cylindrical member.

A developing apparatus comprising:

• a developing tank that stores developer that develops a band-shaped photosensitive material having a silver salt containing layer on a base film;
• and
• a photosensitive material turning member disposed in the developing tank, that allows the band-shaped photosensitive material to float with respect to the photosensitive material turning member such that the band-shaped photosensitive material is turned without contacting the photosensitive material turning member, the photosensitive material turning member including:
• a first cylindrical member disposed in a direction crossing a conveying direction of the band-shaped photosensitive material that has, on a surface thereof in a longitudinal direction, a plurality of slit-shaped discharge openings that discharge the processing solution;
• and a second cylindrical member disposed inside the first cylindrical member that has nozzles that eject the processing solution,
• wherein intervals between the discharge openings on a conveying direction upstream side and a conveying-direction downstream side are smaller than intervals between the discharge openings at a conveying-direction middle portion.
