BACKGROUND OF THE INVENTION
The present invention relates to a silver halide photographic light-sensitive material (hereinafter, also simply referred to as a light-sensitive material or a light-sensitive material for the sake of simplicity), and relates to an automatic developing machine for silver halide photographic light-sensitive material that is processed with a processing solution. Specifically, for silver halide photographic light-sensitive materials of various sizes, a stable development processability is obtained, and an automatic processor for silver halide photographic light-sensitive materials that can be processed quickly (hereinafter referred to as an automatic processor for simplification). It may also be called an automatic machine or a developing machine).
[0002]
[Prior art]
The market for so-called photo finishers, which process photo development, is becoming more and more diversified year by year, and is rapidly changing from a laboratory called a lab to a mini-lab that processes at a photo shop. It depends. There are an increasing number of in-store processing at supermarkets and drug stores other than photo shops. Both of them meet the need to be received on the day of development, or to complete the development process while you are shopping and receive a photo print, and there is an increasing demand for such rapid processing. ing.
[0003]
In addition, when developing processing is performed in stores other than photography specialty stores and offices, part-timers and amateurs who are not specialized operators will be processing, dry equipment that does not feel liquid, easy maintenance Downsizing of the equipment is important because of problems such as downsizing, stable processability, and installation space.
[0004]
Usually, in an automatic developing machine for silver halide photographic light-sensitive materials, for example, a color negative film or a color reversal film, in a camera, a device that develops the light-sensitive material previously exposed, and an exposure print such as color paper There is an apparatus having a process for performing a developing process and a process for performing a developing process. In any of the developing processes, there is a processing tank filled with a processing solution, and a method in which a photosensitive material is automatically immersed therein is generally used.
[0005]
In such tank processing, a so-called replenishing method is employed in which a replenisher is replenished to the processing tank according to the processing area information of the photosensitive material, and overflowed to form a steady state (running state). Therefore, since the running state varies depending on the type of photosensitive material to be processed and the daily processing amount, the processing solution must be managed, and a standard-exposed check piece called a control strip is developed every day. Concentrations were managed by comparing the reference values, and depending on the management situation, it was necessary to discharge all the liquids and replace them with new ones.
[0006]
In order not to perform such complicated and specialized management, various methods have been proposed in which a developing solution is supplied to the photosensitive material as much as necessary for use and no tank solution is used. For example, Japanese Patent Application Laid-Open No. 2-79841 proposes a method in which a processing solution is impregnated in a sponge and developed. For example, Japanese Patent Laid-Open No. 2-79844 proposes a method of supplying a processing liquid from a slit-shaped supply port. For example, Japanese Patent Laid-Open No. 9-43814 proposes a method of supplying a developing solution via a gas phase. Furthermore, for example, Japanese Patent Application Laid-Open No. 2-99945 proposes a method of applying a treatment liquid using a roller.
[0007]
[Problems to be solved by the invention]
Such a method of supplying as many necessary processing liquids as possible is problematic in terms of speeding up. In order to increase the speed, a method has also been proposed in which the processing liquid is divided into a plurality of parts, each of which is concentrated and supplied separately (Japanese Patent Application No. 9-243034).
[0008]
However, in such a supply method, it is necessary to separately supply a plurality of solutions to the photosensitive material, and a plurality of supply means are required, which increases the scale of the apparatus and is difficult to control. Further, there is a drawback that processing unevenness is likely to occur due to the mixing state of a plurality of partial solutions on the surface of the photosensitive material or in the emulsion film of the photosensitive material. Although it is conceivable to supply a premixed mixture, it has been found that precipitation occurs in the case of a concentrated liquid when left for a certain period of time.

The contact angle of the coating roller with the treatment liquid was determined by using the same material and forming method as the roller surface, “New Experimental Chemistry Course 18 Interface and Colloid”, page 97 (October 20, 1977 Maruzen) Issued) is a contact angle measurement method based on the droplet method. That is, a flat specimen having a smooth surface finish is placed horizontally in a container filled with saturated vapor of the liquid to be measured as shown in FIG. 6 (a), and a small amount of liquid droplets are placed thereon using a syringe. to make. The size of the droplet is such that the contact diameter is about 3 mm or less (there is a report that the droplet volume may be 0.1 cm ³ or less).
