Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic developing machine for a silver halide photographic light-sensitive material (hereinafter referred to simply as a light-sensitive material or a light-sensitive material for the sake of simplicity). For the sake of simplicity, it may be referred to as an automatic developing machine, a self-developing machine or a developing machine). In particular, rapid processing is possible, and processing unevenness and oxidative deterioration of the processing solution are improved to obtain stable processing performance. The present invention relates to an automatic processor for silver halide photographic materials.

2. Description of the Related Art A silver halide photographic light-sensitive material is, for example, a silver halide photographic light-sensitive material which is transported by a roller transport mechanism and has a sufficient amount of silver halide stored in a processing tank such as a developing tank or a bleach-fixing layer. It is immersed in a processing solution for photographic light-sensitive materials (hereinafter simply referred to as a processing solution for simplicity) for a predetermined period of time for processing. The processing of the silver halide photographic light-sensitive material consumes the effective components in the processing solution stored in the processing tank, and thus causes deterioration of the processing solution due to fatigue. Further, as in the case where the developer is alkali, for example, carbon dioxide gas in the air is absorbed and neutralization reaction takes place over time, thereby deteriorating due to a decrease in alkalinity, fatigue over time caused by oxidation by oxygen, and the like.

For this purpose, as described in, for example, Japanese Patent Application Laid-Open No. 3-59655, an application roller is arranged in a conveying path of a silver halide photographic light-sensitive material, and a supply roller for supplying a processing liquid to the application roller is provided. It has been proposed to provide a processing liquid reservoir between the supply roller and the application roller, and apply and supply the processing liquid to the image forming surface of the silver halide photographic material by rotating the application roller.

However, in such a case, processing unevenness is likely to occur. This tendency is remarkable during rapid processing. In particular, processing unevenness is likely to occur at the edge of the photosensitive material. Also, a sufficient concentration cannot be obtained. Furthermore, the developer stored in the processing tank or the bleach-fixing solution is supplied, so that the composition of the processing tank is liable to change.
Processing stability such as bleach-fixing is also poor. In recent years, a method in which a photosensitive material is cut and then processed for conveyance is often used from the viewpoints of quickness and environmental suitability. In this case, development unevenness at the end is large. In addition, the supply roller and the transport unit may be stained within a long period of time due to the liquid composition. Even in the coating and developing method, processing unevenness occurs and stains also occur.

For this reason, for example, a method of supplying two types of partial liquids for color development to a silver halide photographic light-sensitive material (hereinafter also referred to as a light-sensitive material) via a gas phase (hereinafter also referred to as two-liquid development) has been proposed. JP-A-9-90579 and JP-A-9-9058
No. 0, No. 9-90581, and the like. Although this method certainly improves the processing stability, the problem of uneven processing due to the variation of the degree of mixing of the two liquids depending on the location has not yet been solved. It turned out to be enough.

[0006] From the viewpoint of speed, the method described above employs a method of directly heating the photosensitive material. However, it has been newly found that when the photosensitive material is directly heated, the photosensitive material curls due to heat, causing severe processing unevenness at the end of the photosensitive material.

The present invention has been made in view of such a situation. First, processing unevenness due to a change in the degree of mixing of the partial liquids is prevented, and secondly, processing unevenness at the edge of the photosensitive material.

The contact angle of the coating roller with the treatment liquid was determined by using a plate sample obtained by the same material and the same forming method as the roller surface, "New Experimental Chemistry Course 18: Interface and Colloid", page 97 (October, 1977). The contact angle is measured based on the droplet method according to the method of measuring contact angles described in Mar. 20, Maruzen.

The size of the droplet should be such that the contact diameter is about 3 mm or less (some reports indicate that the droplet volume should be 0.1 cm ³ or less). The contact angle is generally measured by a reading microscope equipped with a goniometer (magnification: about 20 times). FIG. 13B illustrates the principle.
The liquid is illuminated from the front with light passing through opalescent glass or parallel light passing through heat ray absorbing glass. The measurement accuracy is ± 1 °, and if possible, it can be ± 0.5 °. Measure the left and right angles of the droplet, and if they differ significantly, discard the measurements from that droplet. The angle of the droplet is measured by adding an additional amount of the droplet or leaving the droplet for a while after the droplet is formed to check whether or not the angle has changed. In addition, measurement is performed at several different places on the same solid surface, and at least ten values are obtained to obtain an average value. The water used for the measurement shall be distilled water.

It is preferable that the heating means has a heating control means for controlling the heating means to heat based on the presence information of the silver halide photographic light-sensitive material, because unnecessary heating can be prevented. This is to detect the presence of a silver halide photographic light-sensitive material at a predetermined position upstream of a heating section of a heating means in a transportation direction of the transportation means with a conveying means for conveying the silver halide photographic light-sensitive material at a predetermined conveyance speed. This can be achieved by having photosensitive material detecting means and controlling the heating control means based on the detection of the photosensitive material detecting means. The control in this case is performed immediately after the photosensitive material detecting means detects the presence of the silver halide photographic material at the predetermined position from the absence, or
