Description: FIELD OF THE INVENTION The present invention relates to an image forming method for silver halide color photographic materials (hereinafter also simply referred to as 'light-sensitive materials') and, particularly, to an image forming method for light-sensitive materials in which stain can be inhibited form producing in an unexposed area of the light-sensitive material in storage and rapid processing can be performed. BACKGROUND OF THE INVENTION Light-sensitive material processing basically comprises color developing and desilvering processes; desilvering comprises bleaching and fixing processes or a bleach-fixing process. Rinsing, stabilization and other processes may be added. In processing solution with bleaching capability used to desilver light-sensitive materials, ferricyanates, bichromates, and other inorganic oxidizing agents have conventionally been widely used to bleach image silver. However, some critical drawbacks are pointed out in processing solutions with bleaching capability containing these inorganic oxidizing agents. For example, ferricyanates and bichromates are undersirable in preventing environmental pollution in that they may be decomposed by light to produce harmful cyan ions or hexavalent chromium ions, though they are relatively high in image silver bleaching power. Another drawback is that it is difficult to regenerate for reusing these processing solutions without discarding the waste liquid after processing. In response to the requirements of less problems of environmental pollution, rapid and simple processing, reuse of waste liquid, and others, processing solutions containing metal complex salts of organic acids, such as aminopolycarboxylic acid, as oxidizing agent have become used. However, such processing solutions are faulty in that the bleaching rate (oxidation rate) of image silver (metallic silver) formed in the developing process is low due to weak oxidation power. For example, iron (III) complex salt of ethylenediaminetetraacetic acid, considered relatively strong in bleaching power among metal complex salts of aminopolycarboxylic acid, is now in practical use in bleaching solutions and bleach-fixers, but it is faulty in that bleaching power is insufficient and much time is taken in the bleaching process when used for high-sensitivity silver halide color photographic light-sensitive materials composed mainly of a silver bromide or silver iodobromide emulsion, specifically silver-rich color paper for picture taking and color negative and color reversal films for picture taking which contain silver iodide. In addition, developing methods using automatic developing machine etc. to continuously process large amounts of light-sensitive materials necessitate a means of keeping the processing solution components in a given range of concentration to avoid reduction of bleacher performance due to changes in component concentrations. To meet this requirement, as well as to increase economy and prevent environmental pollution, some methods were proposed, including the method in which concentrated replenishers are added in small amounts and the method in which overflow solutions are supplemented with regenerating agents and then reused as replenishers. As regards bleachers, a method is now in practical use in which a ferrous complex salt of organic acid formed in bleaching developed silver, e.g. iron (II) complex salt of ethylenediaminetetraacetic acid, is oxidized by airation to iron (III) complex salt of ethylenediaminetetraacetic acid, i.e. ferric complex salt of organic acid, and a ragenerating agent is added to replenish the deficient components, then the solution is used as a replenisher. In recent years, however, what is called compact-labos (also called minilabos) have become widely established with the aim of reducing processing time for silver halide color photographic light-sensitive materials and delivery cost; in these labos, there are severe needs of process simplification and reduction of developing machine installation space, so regeneration is unsuitable since it necessitates troublesome procedures and maintenance, as well as additional processing space. It is therefore preferable to use the replenishing method with small amounts of thick replenishers without regenerating process; however, when the amount of replenisher is extremely small, there occurs an increase in the concentration of color developer components transferred to the bleaching solution, and the solution becomes likely to be affected by evaporative concentration; these increase the accumulation of color developer components. As stated above, when the color developer component concentration in the bleaching solution increases, there occurs an increase in the ratio of contaminant reducing components, such as color developing agent and sulfites, bleaching reaction is inhibited, and what is called desilvering failure becomes likely to occur. To overcome these drawbacks, it was proposed to use ferric complex salts of aminopolycarboxylic acid disclosed in Research Disclosure No. 24023 and Japanese Patent Publication Open to Public Inspection No. 62-222252/1987 and their mixtures. However, even this method proved to have various drawbacks. For example, ferric propylenediaminetetraacetic acid complex salts are described in the above-given literatures or in the patent publications laid open to public inspection. Such complex salts will produce the so-called sulfurization phenomenon which will decompose thiosulfate that is to serve as a fixing agent, when the complex salts adhered to a light-sensitive material are brought together into a successive fixing or bleach-fixing solution during they are processed, though such complex salts have a strong oxidizing capability. In particular, the above-mentioned disadvantage will be more emphasized when reducing a replenishing amount of a fixing or bleach-fixing solution. In recent years, 'mini-labs' tend to use the so-called waterless treatment, namely, a stabilizing treatment, in which any washing treatment is not carried out, but specific chemicals are used with a great reduction of washing water. In this treatment, unexposed areas tend to be seriously stained while allowing to stand. This tendency is getting more emphasized recently in rapid processing. JP-A-60-140 345 provides a method for processing a light-sensitive material wherein desirable bleaching and fixing can be conducted without creating a yellowish stain even when processed with a bleaching solution using a ferric salt. This can be achieved in a method for processing a light-sensitive material, wherein said light-sensitive material containing at least one kind of cyan couplers specified therein, is processed after imagewise exposure with a developing solution, a bleaching solution and a fixing solution, said bleaching solution and/or fixing solution preferably comprising a ferric salt of an organic acid specified at description pages 4 to 6 of said JP-A. As fixing solution there can be used solutions comprising compounds forming a water-soluble silver complex through reaction with silver halide such as thiosulfates, thiocyanates, thiourea, thioether, bromide compounds having high concentration and iodide compounds (see page 7, fourth para. from bottom). In the Examples of said JP-A only thiosulfate is used in the fixing solution. Further, in contrast to the present invention no replenishing amounts of the bleaching solution are mentioned in said JP-A. SUMMARY OF THE INVENTION It is, therefore, an object of the invention to provide an improved method of image forming for a light-sensitive material, which is capable of rapidly processing the light-sensitive material, excellently preventing stains in unexposed areas easpecially in allowing the light-sensitive material to stand, and preventing a precipitation. Another object of the invention is to provide a method of image forming of a light-sensitive material, which is excellent in processing stability and capable of carrying out a continuous processing extending over a long period of time and a small quantity processing on occasions, either. The above objects of the invention is achieved by an image forming method comprising the steps of developing an imagewise exposed silver halide color photographic light-sensitive material with a color developer bleaching the silver halide color photographic light-sensitive material, immediately after the developing step, with a bleaching solution, and treating the silver halide color photographic light-sensitive material, after the bleaching step, with a solution having fixing capability, wherein the bleaching solution contains a ferric complex salt of a compound represented by the following formula A, said bleaching solution is replenished in an amount of 20 to 500 ml/m² of material, and the solution having fixing capability contains at least one of thiocyanate and an iodide in a total amount of not less than 0.5 mol per liter of the solution, wherein A₁ through A₄ are each a -CH₂OH group, a -COOM group or a -PO₃M¹M₂ group, which may be the same with or different from each other, M, M¹ and M² are each a hydrogen atom, a sodium atom, a potassium atom or an ammonium group; X is a substituted or unsubstituted alkylene group having 3 to 6 carbon atoms.

The above-mentioned bleach accelerators may be used independently or in combination. Usually, a good result may be obtained when they are added in an amount within the range of about 0.01 to 100 g per liter of a bleach-fixing solution.

Further, the bleaching solutions are allowed to contain a variety of optical brightening agents, defoaming agents, surface active agents and antimolding agents. When the processing solution with fixing capability is a bleach-fixer, it is preferable to use a ferric complex salt of aminocarboxylic acid or aminophosphonic acid as bleaching agent in the bleach-fixer.

When these salts are used in replenishers, it is desirable to use them at the upper limit of solubility to minimize the amount of replenishment.

The typical examples of the thiocyanates each relating to the invention include ammonium thiocyanate, potassium thiocyanate, sodium thiocyanate and so forth. The typical examples of the iodides each relating to the invention include ammonium iodide, potassium iodide, sodium iodide and so forth. It is also allowed to use the above-mentioned fixing agents upon mixing together with thosulfates such as ammonium thiosulfate which is ordinarily used or with the above-mentioned thiocyanates and iodides each relating to the invention. In this invention, it is necessary that a total mole number of the thiocyanates and iodides each relating to the invention should be not less than 0.5 mol/liter.

It is also desirable to add a large amount of alkali halides or ammonium halides including, for example, rehalogenizers such as potassium bromide, sodium bromide, sodium chloride, ammonium bromide and so forth. It is further allowed to selectively add pH buffers such as borate, oxalate, acetate, carbonate, phosphate and so forth, and the well-known additives which are usually added to fixing solutions and bleach-fixing solutions, such as alkylamines, polyethylene oxides and so forth. In the present invention, air or oxygen blowing may be conducted in the processing bath and replenisher storage tank,or a suitable oxidizing agent, such as hydrogen peroxide, bromate or persulfate may be added to increase bleacher or bleach-fixer activities. In the method of the present invention, silver may be recovered from the fixer or bleach-fixer by a known method. Examples of methods which serve well for this purpose include the electrolysis method of French Patent No. 2,299,667, precipitation method of Japanese Patent Publication Open to Public Inspection No. 73037/1977, West German Patent No. 2,311,220, ion exchange method of Japanese Patent Publication Open to Public Inspection No. 17114/1976, West Germany Patent No. 2,548,237 and metal replacement method of British Patent No. 1,353,805. In-line silver recovery from the tank solution is preferable, since rapid processing is facilitated, but silver may be recovered from overflow waste liquid and then regenerated. The desired effect of the invention is enhanced when the fixer or bleach-fixer of the invention is replenished at less than 800 mℓ per m² light-sensitive material; a noticeable effect is obtained at 20 to 650 mℓ, particularly 30 to 400 mℓ per m² light-sensitive material. A processing solution having a fixing capability, such as a fixer or bleach-fixer, should preferably contain a compound represented by the following formula FA.

Bleaching time can be arbitrarily chosen in the above range of total time; for the desired purpose of the invention, it is preferable that bleaching time be not more than 1 min 30 sec, more preferably 10 to 70 sec, still more preferably 20 to 55 sec. Processing time for the processing solution with fixing capability can be arbitrarily chosen in the above range of total time; it is preferable that the processing time be not more than 3 min 10 sec, more preferably 10 sec to 2 min 40 sec, still more preferably 20 sec to 2 min 10 sec. In the processing method of the present invention, it is preferable to conduct forced agitation of the bleaching solution, fixer and bleach-fixer. This is not only because the desired effect of the invention is enhanced but also because rapid processing is facilitated. Here, forced agitation does not imply ordinary diffusive migration of solution but the use of a method of agitation to forcedly agitate the solution. The methods of forced agitation which can be used are as follows: 1.High pressure spraying method or spray agitation method 2. Air bubbling method 3.Ultrasonic oscillation method 4. Vibration method In the high pressure spraying method, the processing solution is sprayed directly to the light-sensitive material via a spray nozzle at a dischrge pressure of not less than 0.1 Kg/cm² in the processing solution. In the spray agitation method, the processing solution is sprayed via a spray nozzle at a discharge pressure of not less than 0.1 Kg/cm² in the processing solution for agitating the solution. In these methods, a pressure pump or flow supply pump is normally used as pressure source. pressure pumps include plunger pumps, gear pumps, magnet pumps, and cascade pumps; example of available products include models manufactured by Maruyama Seisakushyo, such as 15-LPM, 10-BFM, 20-BFM, AND 25-BFM. Examples of flow supply pumps include models manufactured by Iwaki K.K., such as MD-30, MD-56, MDK-25; and MDK-32. Nozzles and spray nozzles are available in various types, including the straight spray type, fan type, round type, entire surface type, and circular type; the effect is enhanced with the increase in impact force and thus with the increase in the number of microvibrations in the subject light-sensitive material. Spray impact force depends mainly on flow rate (ℓ/min.) and spray pressure (kg/c²; therefore, a pressurizer is needed which permits pressure regulation in proportion to the number of spray nozzles to maximize the effect. The ideal pressure is 0.3 to 10 kg/cm²; smaller pressure values give no effect, while greater pressure values may cause damages or ruptures in the light-sensitive material. In the air bubbling method, a sparger is placed at the bottom of the lower transport roller of the processing solution tank, and air or inert gas is supplied to the sparger; the light-sensitive material is vibrated by bubbles discharged from the sparger outlet and the processing solution is thus brought into efficient contact with the top, back, and side surfaces of the light-sensitive material. For the sparger, anticorrosive materials are suitable, e.g. hard vinyl chloride, polyethylene-coated stainless steel, and sintered metals. The outlet is made to have a diameter such that the discharged bubbles are 2 to 30 mm in size; better results are obtained when the outlet diameter is such that the discharged bubbles are 5 to 15 mm in size. Means of air supply include air compressors, e.g. Bebicon (0.4 KW, BU7TL), manufactured by Hitachi, Ltd., and air pumps, e.g. air pumps manufactured by Iwaki K.K. (Ap 220). Air flow rate must be 2 to 30 l/min. for each rack of the automatic processor; better results are obtained at 5 to 20 l/min. It is necessary to regulate the amount of air or inert gas according to the size of processing solution tank and the amount of light-sensicive material, but it is preferable that air or inert gas be supplied so that the amplitude of vibration of the light-sensitive material is 0.2 to 20 mm. In the ultrasonic oscillation method, an ultrasonic oscillator, placed at the bottom or in the side wall space of the processing solution tank of automatic developer, is used to apply ultrasonic waves to the light-sensitive material to increase developing acceleration efficiency. Ultrasonic oscillators which can be used include the magnetostrictive nickel oscillator (horn type) and magnetostrictive barium titanate oscillator (holder type), both manufactured by Cho-onpa Kogyo K.K. Oscillator frequency is normally 5 to 1000 KHz; however, from the viewpoint of enhancement of the effect of the present invention and prevention of damages on the automatic processor, it is preferable that the frequency be 10 to 50 KHz. As regards the application of ultrasonic waves to the light-sensitive material, it may be achieved directly or indirectly using a reflector, but direct application is preferred since ultrasonic waves attenuate in proportion to the application distance. It is recommended that application time be at least 1 second. In the case of partial application, it may be conducted whenever in the initial, middle, and last stages of processing. In the vibration method, the light-sensitive material is vibrated between the upper and lower rollers in the processing solution tank of automatic processor to increase immersion processing efficiency. Examples of vibrators which can be normally used as vibration sources include V-2B and V-4B models, manufactured by Shinko Electric Co., Ltd. The vibrator must be fixed onto the upper portion of the immersion tank of automatic processor so that the vibrating needle is located in the back side of the light-sensitive material. It is preferable that the frequency be 100 to 10000 cycle/min; the most preferable range is from 500 to 6000 cycle/min. The amplitude of the subject light-sensitive material is 0.2 to 30 mm preferably 1 to 20 mm; smaller amplitude given no effect, while greater amlitude may damage the light-sensitive material. The number of vibrating elements varies depending on the size of the automatic processor, when a multitank processing unit is used, good results are obtained by allotting at least one element to each tank. In the method of the invention, the bleaching process is carried out immediately after the developing process without any treatment between these processes. Examples of preferred procedures of the processing method of the present invention are given below, but the invention is not limited thereby. (1)Color developing → bleaching → fixing → washing (2) Color developing → bleaching → fixing → washing → stabilization (3)Color developing → bleaching → fixing → stabilization (4)Color developing → bleaching → fixing → 1st stabilization → 2nd stabilization (5) Color developing → bleaching → bleach-fixing → washing (6) Color developing → bleaching → bleaching-fixing → washing → stabilization (7) Color developing → bleaching → bleach-fixing → stabilization (8)Color developing → bleaching → bleach-fixing → 1st stabilization → 2nd stabilization, subsequent 3rd stabilization, if needed Of these procedures, (3), (4), (7) and (8) are preferable; particularly, (3) and (4) are more preferable. Another preferred mode of the processing method of the invention is that in which partial or entire portion of overflow liquid of th color developer is flown into the bleacher; sludge formation in the bleacher is reduced when a given amount of the color developer is flown into the bleacher.

The flow-in amount varies with the type of light-sensitive material, transport rate and method, and lignt-sensitive material surface squeezing method of automatic developing machine; in the case of color light-sensitive materials for picture taking or ordinary color roll films, the flow-in amount is usually 50 to 150 mℓ/m²; the effect of the present invention becomes more noticeable under this condition when the amount of replenisher is 50 mℓ to 4.0 ℓ/m², and it becomes still more noticeable when the amount of replenisher is 200 to 1500 mℓ/m².
