addition of demineralized water in order to make 1 l of fixer solution; pH 5.43. |
For still lower replenishing amounts differences in pH value at the start and after seasoning may even exceed 0.6 pH units.
Application of a replenisher having too low a pH value results in too low a pH value after seasoning, whereas application of a replenisher having too high a pH value results in other problems as will be made clear in the Examples 5 and 6.

Claims (11)
- Method of processing in a processor an image-wise exposed black-and-white light-sensitive silver halide photographic material comprising the steps of developing in a developing solution and fixing in a fixer solution, characterized in that upon starting of the processing the said fixer solution comprises a mixture of a fixer starter solution and a fixer replenisher solution, in that said fixer solution is replenished with the said fixer replenishing solution and in that the said fixer starter solution is a developing solution.
- Method according to claim 1, comprising the step of mixing said fixer starter solution and a fixer replenisher solution in a fixer unit or tank of the said processor.
- Method according to claim 2, wherein said fixer starter solution is mixed with the fixer replenishing solution in the processor before starting processing.
- Method according to any of claims 1 to 3, wherein the fixer starter solution comprises developing agent(s) in a molar amount versus thiosulphate ions in the fixer replenisher solution of from 0.015 up to 0.080.
- Method according to any of claims 1 to 4, wherein said fixer starter solution alters pH to a value in the range from - 0.3 up to + 0.3 units of the pH of the fixer solution after seasoning.
- Method according to any of claims 1 to 5, wherein said fixer solution is free from aluminum ions.
- Method according to any of claims 1 to 6, wherein an amount of fixer starter solution is proportional to tank volume of the fixer solution in the processor.
- Method according to any of claims 1 to 7, wherein an amount of fixer starter solution is less than 10 % of volume of replenisher solution with which it is mixed upon starting processing.
- Method according to any of claims 1 to 8, wherein said fixer is replenished with fixer replenisher solution in an amount of from 20 up to 100 ml/g of silver to be fixed.
- Method according to any of claims 1 to 9, further comprising the step of developing in a developing solution comprising one or more developing agents selected from the group consisting of hydroquinone,
1-phenyl-5-pyrazolidine-1-one, ascorbic acid, reductic acid, stereoisomers or derivatives thereof. - Method according to any of claims 1 to 10, comprising the steps of developing, rinsing, fixing and drying, wherein the total processing time of these steps is from 30 up to 300 seconds.
