FIG. 1 shows an embodiment of a developing tank having a processing path formed by a space having a slit-like cross section as a processing tank having a developing function used for carrying out the processing method of the photosensitive material of the present invention. ing.

By using the developing tank having such a structure, the amount of the developing solution can be reduced, and the contact surface between the air and the developing solution is reduced, so that the deterioration of the developing solution can be prevented.

The developing tank shown in FIG. 1 has a configuration in which a rack 14 is inserted into a housing 12 whose upper end is open.

The rack 14 is provided with a pair of side plates, and the pair of side plates is connected by a block body 20, and FIG. 1 shows only one side plate 16 of the pair of side plates.

Near the middle of the space of the block body 20, the block body 50 is installed in the vertical direction such that the carry-in rollers 52 and 56 and the carry-out rollers 54 and 58 are installed on both sides.

The transport roller 32 and the transport roller 48 are provided in the block body 50.

A processing path 46 having a slit-like cross section is formed by the block bodies 20 and 50, the reversing roller 24, and the transport rollers 28, 30, 32 and 48.

The cross section of the slit-like processing path 46, which is the passage portion of the photosensitive material S, may have a gap of about 0.5 to 30 mm, preferably about 0.8 to 8 mm.

With such a gap, the photosensitive material S can be transported without any trouble, and the occurrence of scratches due to transport can be prevented.

In the above, the block bodies 20 and 50 may be solid or hollow, but have a hollow structure as illustrated,
It is preferable that it is produced by blow molding.

Blow molding is a method in which a thermoplastic resin is preformed in a tube shape by extrusion or injection to form a parison, which is sandwiched between molds, air is blown into the interior, inflated, and cooled and solidified. For details, reference can be made to books such as “Handbook of Plastics Processing Technology (New Edition)” by Nikkan Kogyo Shimbun, etc. Also in the present invention, the above-described block bodies 20 and 50 can be manufactured according to such known techniques.

It is circulated through a pipe.

In this circulation, in addition to the developer 10 from the processing path 46, for example, a replenisher may be injected from the R direction in the drawing.

On the other hand, the pump 45, on the unloading side of the photosensitive material S, removes the developing solution 10 taken out from the vicinity of the transport roller 30 to a block body.
Nozzle hole 202 formed on the side of processing path 46 of 20
And circulates through a pipe so as to jet the jet.

In the above, the circulation amount may be such that the entire amount of the developer filled in the processing path is replaced within 0.5 minutes,
It may be about 0.5 to 60 / min, preferably about 2 to 8 / min.

With such a circulating amount, the liquid composition of the developing solution becomes uniform, the occurrence of tailing is suppressed, and the photographic properties such as the sensitivity and the gradation are improved.

In such a case, the nozzle holes 201 and 202 are provided in the block body 20 facing the emulsion surface of the photosensitive material S.

Although the nozzle holes 201 and 202 are preferably provided in the whole area in the processing path as shown in the drawing, in some cases, the nozzle holes 201 and 202 may be provided in the first half of the processing path, for example, about 1/4 to 1/2. Good.

Then, the nozzle holes 201 and 202 allow the developing solution 10 to pass through the photosensitive material S
In order to achieve the same parallel flow as the conveying direction of the photosensitive material S, it is preferable that the opening is provided inclining in the conveying direction of the photosensitive material S.

In this case, the nozzle hole may be spot-shaped as shown in FIG. 3a or slit-shaped as shown in FIGS. 3b and 3c.

In this case, near the loading rollers 52 and 56, the photosensitive material S is transported so that the emulsion surface faces downward (toward the loading roller 52).
In the transporting process, the developing solution is circulated by the pump 40 and jetted from the nozzle hole 201 onto the emulsion surface of the photosensitive material S.

By jetting the emulsion surface in this manner, the processing liquid becomes uniform, and the processing chemicals in the processing liquid permeate into the light-sensitive material film more quickly, thereby replacing the fatigued chemicals in the light-sensitive material film with new chemicals. Is obtained, and as a result, photographic properties such as sensitivity and gradation are improved, and the occurrence of tailing is suppressed.
