Description: FIELD OF THE INVENTION The present invention relates to a method of processing a silver halide color photographic light-sensitive material, more specifically, to a method of processing a silver halide color photographic light-sensitive material which effectively prevents the sludging of silver and the occurrence of bleach fogging, and allows processing to be performed rapidly without affecting adversely work environments due to the use of a bleacher having no offensive odor. BACKGROUND OF THE INVENTION Generally, light-sensitive materials that have been exposed to light are then subjected to processing that comprises color developing, desilvering, and rinsing and stabilizing. EP-A-0329052 discloses a method for forming color photographic images comprising steps of exposing a silver halide color photographic light-sensitive material to light, developing the material with a color developer, bleaching the material with a bleaching solution, which bleaching solution comprises a ferric complex salt of a compound of the following formula: wherein A 1 to A 4 are each -CH 2 OH, -COOM or -PO 3 M 1 M 2 group, wherein M, M 1 and M 2 are each a hydrogen atom, a sodium atom, a potassium atom or an ammonium group and X is a substituted or and unsubstituted C 3-5 alkylene group. EP-A-0466372, which falls within the terms of Article 54(3) EPC, discloses a method of processing silver halide color photographic light-sensitive material using a bleaching solution which comprises at least one ferric complex salt of a compound of the following formula: wherein A 1 to A 4 each represent a CH 2 OH, -COOM or a -PO 3 M 1 M 2 group, wherein M, M 1 and M 2 each represent a hydrogen atom, an alkali metal atom or an ammonium group and X represents a substituted or unsubstituted C 3-6 alkylene group. The bleaching solution optionally further comprises a ferric complex salt of a specified di-, tri- or tetra-basic acid. Today, processing of light-sensitive materials is normally performed by photo processing shops. In such shops, processing is conducted continuously by means of automatic developing machines. To satisfy users' increasing demands for more prompt service, these photo processing shops have to complete processing and return films to their customers within a half day; that is, if they receive an order in the morning, they have to hand over a processed film in the evening of the same day. Lately, these shops are often requested to finish the work within only a couple of hours after the receipt of an order. Under such circumstances, the need for a more improved technique for rapid processing is pressing. Meanwhile, Eastman Kodak has proposed Process RA-1, a novel method of processing color paper. It comprises three steps; 45-sec color developing, 45-sec bleach/fixing and 90-sec stabilizing. According to Process RA-1, the total processing time is three minutes, and the processing temperature is 35°C. Conventional methods for rapid processing can be divided into the following three categories: (1) making improvements on light-sensitive materials so that they can be more suited to rapid processing; (2) making improvements on instruments and means employed for processing ; and (3) making improvements on the compositions of processing liquids Methods relating to (1) above include: 1. improving silver halide composition, such as reducing the sizes of silver halide grains [see Japanese Patent Open to Public Inspection (hereinafter abbreviated as Japanese Patent O.P.I. Publication) No. 77223/1976)] or reducing the amount of silver bromide; 2. using additives, such as adding 1-aryl-3-pyrazolidone with a specific structure to a light-sensitive material (see Japanese Patent O.P.I. Publication No. 64339/1981) or adding 1-arylpyrazolidone to a light-sensitive material (Japanese Patent O.P.I. Publication Nos. 144547/1982, 50534/1983, 50535/1983 and 50536/1983); 3. using quick-reacting couplers, such as a quick-reacting yellow coupler (see Japanese Patent Examined Publication No. 10783/1976, Japanese Patent O.P.I. Publication Nos. 123342/1975 and 102636/1976); and 4. reducing the thicknesses of photographic layers (see Japanese Patent Application Specification No. 204992/1985) As for (2), Japanese Patent Application Specification No. 23334/1986 discloses an improved method of stirring processing liquids. Methods belonging to the category (3) include: 1. using development accelerators; 2. increasing the concentration of a developing agent in a developer ; and 3. decreasing the concentration of halide ions, in particular, that of bromide ions. Among various conventional methods for rapid processing, including those mentioned above, especially effective is the use of a light-sensitive material with a higher silver chloride content (see Japanese Patent O.P.I. Publication Nos. 95345/1983, 19140/1985 and 95736/1983). Such light-sensitive materials have recently put on the market (e.g. Ektacolor paper 2001 by Eastman Kodak Company, Konicacolor QA paper by Konica Co.). Meanwhile, in recent years, to reduce processing costs as well as to prevent environmental pollution, desilvering has come to be conducted by using a bleacher and a fixer separately. This tendency is more pronounced in large-scale processing laboratories which have to reduce production costs and are under strict restrictions for pollution control. The use of a bleacher, however, involves various problems. It is generally known that, if a low-silver light-sensitive material having a reflective support, such as color negative paper (hereinafter referred to as color paper), is treated in a bleacher immediately after color development, stains are formed on the surface of the light-sensitive material since a color developing agent that has been soaked into the light-sensitive material is oxidized due to the strong oxidative power of the bleacher. To avoid this problem, color paper, after color developing and before bleaching, is normally subjected to stopping and rinsing to wash away color developer components therefrom. This method is also defective, since it needs the provision of at least two processing liquid tanks between a color developer tank and a bleacher tank, which eventually results in an increase in cost. Under such circumstances, there is a strong demand for a method of processing color paper which can effectively prevent the formation of stains even when the color paper is treated in a bleacher immediately after color development. Another serious problem is that, when color paper is treated in a bleacher, silver chlorobromide that is normally contained in color paper is reacted with a halide contained in a bleacher (e.g. ammonium bromide) to form silver-halogen complexes, which complexes are dissolved in the bleacher, while being diluted partially with a color developer brought into the bleacher tank by the color paper, and then precipitates in the bleacher tank to form sludge. The sludge causes clogging of a filter and other parts of an automatic processing machine, and makes it unable to work. This trouble occurs more frequently when only a small amount of a replenisher is used for a bleacher. Still another problem accompanying the use of a bleacher is the harmful effect of a bleacher to work environments. For use, a bleacher has to be made acidic to maintain its high oxidation potential, and acetic acid is commonly used as a pH controller. Acetic acid tends to vaporize and diffuse with an offensive odor, affecting adversely the health of people working in processing laboratories. SUMMARY OF THE INVENTION One object of the invention is to provide a method of processing a silver halide color photographic light-sensitive material with a reflective support, by which the formation of stains is effectively prevented even though bleaching is conducted immediately after color developing. Another object of the invention is to provide a method of processing a silver halide color photographic light-sensitive material which effectively prevents the sludging of silver in a bleacher. Still another object of the invention is to provide a method of processing a silver halide color photographic light-sensitive material which allows bleaching to be conducted stably for a prolonged period of time and needs only a small amount of a replenisher for a bleacher. Further object of the invention is to provide a method of processing a silver halide color photographic light-sensitive material which ensures good working environments free from the offensive odor of acetic acid. Other objects as well as features and advantages of the invention are apparent from the following description. The above objects can be attained by a method of processing a silver halide color photographic light-sensitive material comprising subjecting a silver halide color photographic light-sensitive material that has been exposed to light to color development to develop dye images, subjecting said light-sensitive material to bleaching with a bleacher to bleach developed silver, followed by treatment with a fixative liquid to fix the dye images, wherein the total silver coverage of said light-sensitive material before processing is not more than 1 g/m 2 , the silver halide emulsion layer comprises silver halide grains having a silver chloride content of not less than 80 mol % and said bleacher contains at least a ferric complex salt of a compound represented by the following Formula [A] and a compound represented by the following Formula [B]: [wherein A 1 to A 4 , whether identical or not, each represent -CH 2 OH, -COOM or -PO 3 M 1 M 2 (wherein M, M 1 and M 2 each represent hydrogen, sodium, potassium or ammonium); and X represents substituted or unsubstituted alkylene having 3 to 6 carbon atoms, Formula [B] A ( C O O M) n [wherein n is 2 or 3; A represents a single bond or an divalent group when n is 2, and represents a trivalent group when n is 3; M represents hydrogen, an alkali metal or ammonium, and M may be either identical or different], and wherein the bleaching solution comprises from 0.05 to 2.0 mol/ℓ of the compound of formula [B].

(I-1) to (I-10), (II-1) to (II-27), (III-1), (III-15), (IV-1) to (IV-3), (V-1) to (V-23), (VI-1) to (VI-17), (VII-1) to (VII-15), (VIII-1) to (VIII-7), (IX-1) to (IX-5) and (A-1) to (A-8), which are described in Japanese Patent Application Specification No. 32501/1988, pp 17 to 39. These compounds are normally employed as a bleach accelerator, and will be referred to as the "bleach accelerator" used in the method of the present invention. These bleach accelerators may be employed either alone or in combination. Good results can be obtained when they are employed in amounts of 0.01 to 100 g per liter of the bleacher. If the amount of the bleach accelerator is too small, its bleach acceleration effect cannot be manifested sufficiently. If employed excessively, the bleach accelerator may precipitate, and eventually lead to the formation of stains in a light-sensitive material. Taking these into consideration, the amount of the bleach accelerator is preferably 0.05 to 50 g, more preferably 0.15 to 15 g, per liter of the bleacher. The bleach accelerator may be added to the bleacher as it is, but is preferably added in the form of a solution obtained by dissolving it in water, an alkali or an organic acid. In dissolution, an organic solvent such as methanol, ethanol and acetone may be used if need arises. The pH of the bleacher is preferably 2.0 to 5.5, more preferably 3.0 to 5.0. Successful desilvering cannot be attained if the pH of the bleacher exceeds 5.5. When the bleacher has a pH lower than 2, though desilvering can be performed sufficiently, a leuco dye may be formed. Bleaching is performed preferably at 20 to 45°C, more preferably 25 to 42°C. Normally, a halide such as ammonium bromide is added to the bleacher used in the method of the invention. Next, the compounds represented by the Formula [B] will be explained in detail. In the Formula [B], n = 2 or 3, A represents a single bond or an divalent group when n is 2, and represents a trivalent group when n is 3. M represents hydrogen, an alkali metal (e.g. sodium or potassium) or ammonium. M may be the same or different. Representative examples of the compounds represented by the Formula [B] are given below. (B-1) HOOCCH 2 C(OH)(COOH)CH 2 COOH (B-2) HOOC(CHOH) 2 COOH (B-3) HOOCCH 2 COOH (B-4) HOOCCH(OH)CH 2 COOH (B-5) HOOCCH=CHCOOH (B-6) HOOCCH 2 CH 2 COOH (B-7) (COOH) 2 (B-10) NaOOCCH=CHCOONa (B-11) KOOCCH=CHCOOK (B-12) H 4 NOOCCH=CHCOONH 4 Of the compounds represented by the Formulae B-1 to 16, preferred are those represented by the Formulae B-1, B-3, B-4 and B-5. Especially preferred are those represented by the Formula B-5. The compounds represented by the Formula [B] may be employed in the form of either an acid or a salt (e.g. potassium salts, sodium salts, ammonium salts, lithium salts, triethanolammonium salts). The compounds represented by the Formula [B] are contained in the bleacher in amounts of 0.05 to 2.0 mols, preferably 0.1 to 1.0 mol, per liter of the bleacher. The bleacher used in the method of the invention may contain a buffer in such an amount as will not affect adversely the effects of the invention. As the buffer, acetic acid is preferred in the invention. Studies made by the inventors have revealed that the above-mentioned unfavorable odor problem ascribable to the use of acetic acid in a bleacher is closely related to the amount and pH of acetic acid. Even if a bleacher contains acetic acid of which the pH is within the scope of the invention, its adverse effects on working environments can be suppressed to a tolerable level as long as the amount does not exceed 0.6 mol/ℓ (preferably 0.5 mol/ℓ or less). In respect of buffer effect and cost, the use of a suitable amount of acetic acid with a suitable pH is advisable. The bleacher used in the method of the invention may further contain a pH buffer consisting of a salt such as boric acid, borax, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate or ammonium hydroxide. The use of two or more buffers in combination is also possible. The bleacher may also contain a fluorescent bleacher, an antifoamer, a surfactant and fungicide. The objects of the invention can be attained more successfully when the amount of ammonium ions contained in the bleacher accounts for 50 mol% or less, preferably 20 mol% or less, more preferably 10 mol% or less, of the total amount of cations contained in the bleacher. Representative examples of the cations to be contained in the bleacher of the invention include ammonium ions, potassium ions, lithium ions, monomethyl ammonium, trimethyl ammonium and triethanol ammonium. The amount of a replenisher for the bleacher is preferably 10 to 200 mℓ, more preferably 20 to 100 mℓ, further more preferably 25 to 80 mℓ, most preferably 30 to 60 mℓ, per square meter of a light-sensitive material. In the method of the invention, it is preferred that a light-sensitive material be treated with the above-mentioned bleacher immediately after color development. For rapid processing, bleaching with the above-mentioned bleacher is followed by treatment with a fixative liquid. In the invention, the fixative liquid means a fixer or a bleach-fixer. Preferred examples of the processing method according to the invention include: (1) Color developing - bleaching - fixing - rinsing (2) Color developing - bleaching - fixing - rinsing - stabilizing (3) Color developing - bleaching - fixing - stabilizing (4) Color developing - bleaching - fixing - 1st stabilizing - 2nd stabilizing (5) Color developing - bleaching - bleach - fixing - rinsing (6) Color developing - bleaching - bleach - fixing - rinsing - stabilizing (7) Color developing - bleaching - bleach - fixing - stabilizing (8) Color developing - bleaching - bleach - fixing - 1st stabilizing - 2nd stabilizing Of the above methods, (3), (4), (6), (7) and (8) are preferable. Methods (3), (4) and (7) are more preferable. Method (3) is most preferable. A fixer or a bleach-fixer to be employed in the method of the invention must contain a fixing agent. Suitable fixing agents include thiosulfates such as potassium thiosulfate, sodium thiosulfate, ammonium thiosulfate; thiocyanates such as potassium thiocyanate, sodium thiocyanate and ammonium thiocyanate; thiourea; and thioethers. Of them, thiosulfates and thiocyanates are preferred. Stain formation can be suppressed, though not greatly, when the amount of ammonium ions contained in the fixer or the bleach-fixer accounts for not more than 50%, preferably not more than 20%, of the total amount of cations contained in the fixer of the bleach-fixer. The fixer or the bleach-fixer may further contain a pH buffer consisting of a sulfite such as ammonium sulfite, potassium sulfite, ammonium bisulfite, potassium bisulfite, sodium bisulfite, ammonium metabisulfite, potassium metabisulfite and sodium metabisulfite, or a salt such as boric acid, borax, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, acetic acid, sodium acetate or ammonium hydroxide. The use of two or more buffers in combination is possible. It is also possible to add to the fixer or the bleach-fixer a large amount of a re-halogenating agent such as alkali halides and ammonium halides (e.g. potassium bromide, sodium bromide, sodium chloride, ammonium bromide). Other additives that have been conventionally employed for a fixer or a bleach-fixer may also be added to the fixer or the bleach-fixer to be used in the invention. Such additives include a pH buffer such as borates, oxalates, acetates, carbonates and phosphates; alkylamines and polyethylene oxides. The above fixing agents are employed normally in amounts of not less than 0.1 mol, preferably 0.2 to 3 mols, more preferably 0.25 to 2 mols, most preferably 0.3 to 1.0 mol, per liter of the fixer or the bleach-fixer. To activate the fixer or the bleach-fixer, air or oxygen may be blown into the bath or into the replenisher storage tank. Activation may be performed also by the addition of a suitable oxidant, for instance, hydrogen peroxide, a bromate or a persulfate. In practicing the present invention, unnecessary silver may be recovered from the fixer or the bleach-fixer by known methods, for example, by an electrolysis method (see French Patent No. 2,299,667), a precipitation method (see Japanese Patent O.P.I. Publication No. 73037/1977 and German Patent No. 2,331,220), an ion exchange method (see Japanese Patent Examined Specification No. 17114/1976 and German Patent No. 2,548,237) and a metal substitution method (see British Patent No. 1,353,805). For rapid processing, it is desirable to recover unnecessary silver directly from a fixer (or bleach-fixer) tank by the in-line system. But it is also possible to recover silver particles from an overflow for reusing. The objects of the invention can be attained more successfully when the amount of a replenisher for the fixer or the bleach-fixer is 300 mℓ or less, preferably 20 to 200 mℓ, more preferably 30 to 100 mℓ, per square meter of a light-sensitive material. Bleaching time is not critical, but better results can be obtained when bleaching is performed for 1 minute and 30 seconds or less. Bleaching time is more preferably 10 to 70 seconds, most preferably 15 to 55 seconds. Time for the treatment with a fixative liquid is not limitative, but preferably not longer than 2 minutes, more preferably 5 to 90 seconds, most preferably 10 to 60 seconds. The cross-over time between color developer tank and bleach tank is preferably 10 seconds or less more preferably 7 seconds or less. For the successful attainment of the objects of the invention, and for rapid processing, it is preferred that the bleach, the fixer or the bleach-fixer be subjected to stirring. Stirring, in this context, means stirring performed by stirring means, and does not mean natural diffusion movement of a liquid. Suitable stirring methods include: 1. High-pressure spray method or spray stirring method 2. Air bubbling method 3. Ultrasonic oscillation method 4. Vibration method In the methods (1), a processing liquid (bleach, fixer or bleach-fixer) is sprayed from a spray nozzle or a nozzle, which is being immersed in the liquid, at a pressure of 0.1 kg/cm 2 or larger to a light-sensitive material. As a pressure source, a pressure pump or a liquid transporting pump is generally employed. Examples of pressure pumps include plunger pumps, gear pumps, magnet pumps and cascade pumps. Commercially available pressure pumps are, for instance, 15-LPM, 10-BFM, 20-BFM and 25-BFM manufactured by Maruyama Seisaku sho. MD-30, MD-56, MDH-25 and MDK-32 (manufactured by Iwaki Co. Ltd.) are employable as the liquid-transporting pump. Nozzles and spray nozzles to be employed in the methods (1) are classified, according to the shape or direction of a liquid sprayed, into bee-line types, fan types, circular types, overall types, ring types, or the like. It is preferred that nozzles can give a light-sensitive material an impact sufficient to make the light-sensitive material tremble. The impact strength of a liquid sprayed from a nozzle is dependent mainly on the flow rate of the liquid (ℓ/min) and the pressure of spraying (kg/cm 2 ). For successful stirring, the provision of a pressurizer is needed so that the spraying pressure can be controlled in accordance with the number of nozzles employed. The most preferable spraying pressure is 0.3 to 10 kg/cm 2 . If spraying is performed at a pressure lower than 0.3 kg/cm 2 , stirring will be unsuccessful. A pressure higher than 10 kg/cm 2 may result in the formation of scratches or the destruction of a light-sensitive material. In the air bubbling method, air or an inert gas is supplied to a sparger provided at the bottom of a conveying roller in a processing liquid tank, and bubbles ejected from the sparger cause a light-sensitive material to vibrate. By this method, both surfaces of a light-sensitive material as well as the sides thereof can be effectively in touch with a processing liquid. Suitable materials for a sparger include corrosion-proof substances such as rigid vinyl chloride, polyethylene-coated stainless steel and sintered metals. A sparger is perforated such that the size of bubbles ejected from a hole formed by the perforation will be 2 to 30 mm, preferably 5 to 15 mm. The supply of air or an inert gas to a sparger is performed by using an air compressor (e.g. Baby type compressor, manufactured by Hitachi Ltd.) or an air pump (e.g. Ap220, manufactured by Iwaki Co. Ltd.). The amount of air or an inert gas is preferably 21/min to 301/min, more preferably 51/min to 201/min, per rack of an automatic processing machine. The amount of air or an inert gas must be controlled according to the size of a processing liquid tank and the amount of light-sensitive materials to be processed. It is preferable to supply air or an inert gas in such an amount as will make a light-sensitive material vibrate with a vibration amplitude of 0.2 to 20 mm. In the ultrasonic vibration method, an ultrasonic vibrator is provided in a space near the bottom or the side wall of a processing liquid tank, thereby allowing a light-sensitive material to be exposed to ultrasonic waves. The effects of stirring can be enhanced by ultrasonic waves. Usable ultrasonic vibrators include magnetostrictive nickel vibrators (horn type), magnetostrictive ferrite vibrators (plate type) and magnetostrictive barium titanate vibrators (holder type), which are manufactured by Ultrasonic Waves Kogyo Sha. The vibration frequency is normally 5 to 1000 KHz. In the invention, for sufficient stirring as well as for the protection of a light-sensitive material from damage, a ultrasonic vibrator preferably has a frequency of 10 to 50 KHz. A light-sensitive material may be exposed to ultrasonic waves either directly or indirectly through a reflection board provided between a light-sensitive material and a ultrasonic vibrator. In view of a fact that ultrasonic waves decay in proportion to the distance between a vibrator and a light-sensitive material, it is preferable to expose a light-sensitive material directly to ultrasonic waves. Exposure time is preferably 1 second or longer. Partial exposure is also possible. In this case, exposure may be conducted at any stage of processing, i.e., the initial stage, the middle stage, or the final stage of processing. In the vibration method, a light-sensitive material is caused to vibrate between an upper roller and a lower roller provided in a processing liquid tank. As a vibrator, V-2B and V-4B (manufactured by Shinko Denki Co., Ltd) may be employed. A vibrator is fixed at the top of a processing liquid tank, so that it's vibrating tip can be in contact with the backside of a light-sensitive material. Vibration frequency is preferably 100 to 10,000 times per minute, more preferably 500 to 6,000 times per minute. A light-sensitive material vibrates preferably with a vibration amplitude of 0.2 to 30 mm, more preferably 1 to 20 mm. If the vibration amplitude is smaller than 0.2 mm, effective stirring cannot be performed. A vibration amplitude larger than 20 mm may result in the formation of scratches on a light-sensitive material. The number of vibrators is is dependent on the size of an automatic processing machine. When an automatic processing machine consists of a plurality of processing tanks, it is preferred that at least one vibrator be provided in each tank. In the method of the invention, color developing time is preferably 210 seconds or shorter. The color developer to be used in the method of the invention contains an aromatic primary amine-based color developer in an amount preferably 5.0 x 10 -3 mol or more, more preferably 1.0 x 10 -2 mol, most preferably 1.2 x 10 -2 to 2 x 10 -1 mol, per liter of the color developer. As the aromatic primary amine-based color developing agent, use can be made of those which have conventionally been employed in various color photographic processes. These color developing agents include aminophenol or p-phenylenediamine derivatives. Being stable in free states, these compounds are employed in the form of salts, such as hydrochlorides or sulfates. Examples of the aminophenol-based developing agents include o-aminophenol, p-aminophenol, 5-amino-2-oxy-toluene, 2-amino-3-oxy-toluene, and 2-oxy-3-amino-1,4-dimethyl-benzene. To attain the objects of the invention more sufficiently, and to prevent a color developing agent from precipitating on the inner wall of a bleacher tank, it is preferable to employ an aromatic primary amine-based color developing agent with an amino group and at least one water-soluble group. The most preferred example of such agent are those represented by the following Formula [D]: In the formula, R 1 represents hydrogen, halogen or alkyl.

If the silver halide grains used according to the invention comprise solid solution crystals such as silver chlorobromide or silver chloroiodobromide, it is preferred that silver bromide or silver iodide be localized in a specific site of each crystal. When silver halide grains contained in a light-sensitive material to be processed by the method of the invention is silver chlorobromide grains, it is preferred that silver bromide be localized at the apex or in the vicinity of the apex of each crystal. Such silver halide grains can be prepared by allowing a sensitizing dye or an inhibitor to be adsorbed on the surfaces of silver chloride or silver chlorobromide grains and adding silver bromide fine grains for ripening. Instead of the addition of silver bromide fine particles, a solution of a water-soluble bromide can be added for halogen substitution. When the silver halide grains used according to the invention are silver chloroiodobromide grains, it is preferred that silver iodide be localized in the interior portion of each grain. A silver chloroiodobromide grain with silver iodide being localized in its inside can be prepared by allowing silver chloride or silver chlorobromide to be deposited on a core containing silver iodide.

Publication Nos. 11935/1983, 11936/1983, 11937/1983, 108528/1983, 163046/1987, 41845/1988 and 212932/1988, octahedral or tabular grains can be prepared by growing crystals in the presence of an adsorptive sensitizing dye or an inhibitor. The average grain size of the silver halide grains of the invention is preferably 0.05 to 10 µm, more preferably 0.1 to 5 µm, most preferably 0.2 to 3 µm. In combination with the silver halide grains used according to the invention, other silver halide grains can be employed in such an amount as will not affect adversely the effects of the invention. In this case, the weight of the silver halide grains used according to the invention accounts for preferably 30% or more, more preferably 50% or more, most preferably 80% or more, of the total weight of silver halide grains. The localization of halogen in a silver halide grain can be confirmed by an X-ray diffraction method, or by subjecting a dispersion of silver halide grains in a resin to X-ray microanalysis. In the invention, it is preferred that a silver halide emulsion to be employed for preparing a light-sensitive material be monodispersed. A monodispersed emulsion means an emulsion containing 70 wt% or more (preferably 80 wt% or more, more preferably 90 wt% or more) of grains with their sizes falling within the range of 80 to 120% of the average grain size d . The average grain size d is defined as a diameter d 1 with which the product of d 1 3 and the number of grains with a diameter of d 1 n 1 is maximized. The significant figure is calculated down to the third decimal place and the fourth digit is rounded to the nearest whole number. The size of a grain as referred to herein means a diameter of a circle having the same area as the projected image of the grain. Grain size can be measured by a process that comprises: dispersing grains on a flat table (care must be taken not to allow grains to lay one on another), taking an electron microphotograph of grains (magnification: x 10,000 to 50,000); and measuring the diameters of 1,000 or more grains (selected arbitrarily) appearing on the photograph, or measuring the areas of projected images of these grains. The silver halide emulsion used according to the invention preferably has a variation coefficient of not more than 20%, more preferably not more than 15%, wherein the variation coefficient is defined by the following equation: Standard deviation of grain size Average grain size x 100 = Variation coefficient (%) In the above equation, the average grain size is an arithmetic average.

An emulsion containing silver chloride as its main component can be chemically sensitized. As a chemical sensitizer, use can be made of sulfur-containing compounds such as allylthiocyanates, allylthioureas and thiosulfates. A reducing agent may be employed as a chemical sensitizer. Suitable reducing agents are silver compounds described in Belgian Patent Nos. 493,464 and 568,687 and polyamines such as diethylenetriamine and aminomethylsulfinic acid derivatives described in Belgian Patent No. 547,323. Noble metals such as gold, platinum, palladium, iridium, ruthenium and rhodium and noble metal compounds are also usable as sensitizers. Chemical sensitization with these noble metals and noble metal compounds is discussed in R. Koslovsky's report printed in Z. Wiss. Photo., 46, pp. 65-72 (1951). Also see Research Disclosure No. 17643, Section III for details. The emulsion consisting mainly of silver chloride can be optically sensitized by using conventional optical sensitizers such as normal polymethine dyes (e.g. nitrocyanine, basic or acidic carbocyanine, rhodacyanine, hemicyanine), styryl dyes, oxonol and related compounds. See F.M. Hamer, "The Cyanine Dyes and Related Compounds" (1964), Ullmanns Enzyklopädie der Technischen Chemie, 4th ed., Vol. 18, pp. 431-432, and Research Disclosure No. 17643, Section IV. The emulsion consisting mainly of silver chloride may contain an antifoggant and a stabilizer which have conventionally been employed in the industry. Azaindene, in particular, tetraazaindene and pentaindene, is suitable as the stabilizer. Tetraazaindene or pentaazaindene substituted with a hydroxyl group or an amino group is especially preferable. These compounds are described in a Birr's report Printed in Z. Wiss. Photo, 47 , 1952, pp. 2-58, and Research Disclosure No. 17643, Section IV. Incorporation of ingredients, including couplers and additives, in a light-sensitive material can be performed in normal ways. See U.S. Patent Nos. 2,322,027, 2,533,514, 3,689,271, 3,764,336 and 3,765,897. A coupler and a UV absorber may be contained in a light-sensitive material in the form of a charged latex. See German Patent O.P.I. Publication No. 2,541,274 and European Patent No. 14,921 for details. Ingredients may be incorporated in a light-sensitive material in the form of a polymer. See German Patent O.P.I. Publication No. 2,044,992 and U.S. Patent Nos. 3,370,952 and 4,080,211. The support of a light-sensitive material which is to be processed by the method of the invention is reflective. As compared with transmissible supports, reflective supports tend to cause the formation of stains in the white background of a photoprint. The commercial value of a photoprint is significantly impaired by such stains. The present invention has been made to solve the problem involved in the use of reflective supports. As the reflective support, use can be made of a paper support coated with a polyolefin, in particular, polyethylene or polypropylene. Examples of such polyolefin-coated paper support are given in Research Disclosure No. 17643, Section VI. Also usable are synthetic polyester films which have been rendered opaque by adding a white pigment, followed by molecular orientation; and synthetic polyester films with their one side or both sides being coated with a white pigment. For details, see Japanese Patent O.P.I. Publication No. 72248/1986. In the invention, a silver halide light-sensitive material which contains couplers in its emulsion layers, should be processed by the conventional color development method. The present invention can be applied to color negative paper, color reversal paper and direct positive paper. EXAMPLES The present invention will be described in more detail according to the following examples. Example 1 Both sides of a paper support were coated with polyethylene. Titanium oxide was added to one side. On this titanium oxide-containing polyethylene layer, layers of the following composition were provided in sequence, whereby a silver halide color photographic light-sensitive material of multilayer structure (Sample 1) was obtained. Coating liquids for these layers were prepared by the following methods. 1st Layer: 26.7 g of a yellow coupler (Y-1), 10.0 g of a dye image stabilizer (ST-1), 6.67 g of another dye image stabilizer (ST-2) and 0.67 g of an additive (HQ-1) were dissolved in 6.5 g of a high boiling solvent (DNP) together with 60 mℓ of ethyl acetate. The resulting solution was dispersed in 220 mℓ of a 10% aqueous gelatin solution that contained 7 mℓ of a 20% surfactant (SU-1) and emulsified by means of a ultrasonic homogenizer, whereby a yellow coupler dispersion was obtained. This yellow coupler dispersion was mixed with a blue-sensitive silver halide emulsion (silver content: 10 g) which had been prepared by the method described later, thereby to obtain a coating liquid for the 1st emulsion layer. Coating liquids for the 2nd to 7th layers were prepared in substantially the same manner as in the preparation of the 1st layer. The 2nd, the 4th and the 7th layers each contained a hardener (H-1 for the 2nd and the 4th layers, and H-2 for the 7th layer). The surface tension of each coating liquid was controlled by the addition of surfactants (SU-2, SU-3).

These processing liquids were put in their respective tanks. The above-obtained color paper samples were treated continuously with these liquids, while these liquids were replenished with their respective replenishers by means of a flow pump. Continuous processing was performed until the total amount of the bleach replenisher supplied became three times as large as the capacity of the bleacher tank. After the continuous processing, sludging was examined visually, and evaluated according to the following criterion: 1. no sludging 2. a little sludging 3. considerable sludging 2-1 or 2-3 means a rating between 2 and 1 or 2 and 3. Further, each of the processed samples was examined for the residual silver amount and the reflectance red density (RDmin) of the unexposed portion. Odor from the bleacher tank was checked by five monitors, and evaluated according to the following criterion. a: no odor b: giving out a dim odor c: giving out an offensive odor d: giving out a very offensive odor The results are shown in Table 1. As is evident from Table 1, good results were obtained as to sluding, fogging of the unexposed portion, desilvering and the odor of bleacher, only when a light-sensitive material with a total silver content of 1 g/m 2 or less before processing was treated in a bleacher that contained an organic acid and a specific ferric complex salt of an organic acid (the compounds represented by the Formula [A] or [B]). Example 2 A series of experiments were conducted in substantially the same manner as in Example 1, except that the pH (after the completion of the continuous processing) of the bleacher employed in the experiment Nos. 1 to 6 was varied to those shown in Table 2. The results are shown in Table 2. Experiment No. pH of bleach Sludging RDmin Residual silver amount 2-1 2.0 2 0.04 0 2-2 2.5 1 0.03 0.1 2-3 3.0 1 0.02 0.1 2-4 4.0 1 0.02 0.1 2-5 5.0 1 0.02 0.1 2-6 5.5 2 - 1 0.04 0.3 2-7 6.0 2 0.06 0.5 2-8 7.0 2 0.08 0.7 In the table, 1, 2 and 2-1 each have the same meaning as those in Table 1. The results shown in Table 2 reveal that good results were obtained for sludging, fogging of the unexposed portion and desilvering, when the bleacher had a pH of 2.5 to 5.5 after the completion of the continuous processing. Better results were obtained when the pH was in the range of 3.0 to 5.0. Example 3 A series of experiments were conducted in substantially the same manner as in Example 1, except that the silver chloride contents of the emulsion layers of the color paper samples employed in the experiment Nos. 1 to 6 were varied to those shown in Table 3, and that the evaluation was made for the reflectance blue density (BDmax) of the highest density portion and the residual silver content. The results obtained are summarized in Table 3.

Better results were obtained when this content was 90 mol% or more. Far better results were obtained when this content was 95% mol% or more, and the best results were obtained when this content was 98 mol % or more. Example 4 A series of experiments were conducted in substantially the same manner as in Example 1 or 3, except that the kind of preservative was varied from diethylhydroxylamine (employed in the experiment Nos. 1 to 6) to those shown in Table 4. The amount of the preservative (in terms of the number of mols) was the same as that in Example 1 or 3. The results obtained are shown in Table 4.

Example 5 A series of experiments were conducted in substantially the same manner as in Example 1, except that the kind of cyan coupler was varied from C-1 to those represented by PC-I (C-4, 11, 15, 19, 20) and those represented by PC-II (PC-II-2, 8, 24, 26, 27, 28, 31 and 32). The results obtained demonstrate that, by the use of these cyan couplers, the reflectance red density of the unexposed portion was reduced by 25 to 30% and the residual silver amount was decreased by 15 to 25%.
