DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art In recent years, with the miniaturization of automatic developing machines, the number of minilab shops that perform development processing at stores using miniaturized developing machines has increased rapidly, and recently minilabs have entered into supermarkets other than photo specialty shops. In addition, the miniaturization of minilab operators is becoming more and more advanced, and miniaturization of minilabs and simplification of operation and maintenance are demanded for minilabs.

[0003] In addition, due to the increase in the number of mini-labs, the amount of processing per day per mini-lab decreases, and the frequency of replenishment of the processing liquid decreases due to the reduction in the amount of processing per day. In addition, the processing solution renewal rate decreases, and the processing solution stays in the processing tank for a long period of time. Therefore, there is a problem that the processing solution (especially, the processing solution for color development) is easily concentrated and deteriorated. If the processing solution is deteriorated, the color density is reduced or the whiteness is reduced, making it difficult to maintain stable processing performance.

However, only the technique described in the above-mentioned patent cannot apply and supply the processing solution uniformly at the front end of the silver halide photographic light-sensitive material to be processed, resulting in unevenness. Is a processing solution for color development, it has been found that color development unevenness in the lowermost layer of the processed silver halide color photographic light-sensitive material is remarkable.
In particular, in recent years, in order to reduce the loss of photographic paper as much as possible, cut-and-convey systems in which photographic paper is cut before the baking process and the cut paper is then conveyed to the baking process and the development process are mainly used. Therefore, the occurrence of unevenness in the application of the processing liquid at the leading end of the cut paper becomes a serious problem.

Further, it has been found that it is difficult to maintain stable developability only by the technique described in the above-mentioned patent, and particularly when the development processing time is shortened, development performance cannot be maintained more and more stably. .

Accordingly, an object of the present invention is to provide an automatic developing machine for a silver halide photographic light-sensitive material capable of maintaining a uniform and stable processing performance even when the processing amount of the photographic material is low. It is in.
