Abstract (en)

[origin: EP0589460A1] There is disclosed a processing method for a silver halide light-sensitive material, in which a nitrogen-containing compound is not contained in a fixing solution in order to reduce a nitrogen content in a washing water and a fixing speed is fast even in the case where a replenishing amount is decreased in order to reduce the amount of waste solution. The method is characterized by: 1) a developing solution having a potassium ion concentration of 0.1 mole/liter or less, 2) a fixing solution containing 0.5 to 2.5 mole/liter of sodium thiosulfate and having an ammonium ion concentration of 0.1 mole/liter or less and a water soluble aluminum compound concentration of 0.01 mole/liter or less, 3) a replenishing amount of the fixing solution at 250 ml/m<2> or less. In certain embodiments of the present invention, the photographic material may be dried using the apparatus described in the specification. <IMAGE>
