Abstract
Abstract In the improved method of processing an imagewise exposed silver halide photographic material that has photographic constituent layers on a side of a support with an automatic processor, comprising: circulating a fixing solution in a fixing bath being discharged in a volume of 30-200% per minute of a capacity of said fixing bath and at a flow rate of not less than 20 m per minute, wherein said silver halide photographic material has a gelatin content of not more than 3.0 g/m 2 in said photographic constituent layers, and said photographic constituent layers comprise a silver emulsion layer which contains silver halide grains having a (100) face to (111) face area ratio of not less than 5.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
115 words
A method of processing an imagewise exposed silver halide photographic material that has photographic constituent layers on a side of a support with an automatic processor, comprising: circulating a fixing solution in a fixing bath being discharged in a volume of 30-200% per minute of a capacity of said fixing bath and at a flow rate of not less than 20 m per minute, wherein said silver halide photographic material has a gelatin content of not more than 3.0 g/m 2 in said photographic constituent layers, and said photographic constituent layers comprise a silver emulsion layer which contains silver halide grains having a (100) face to (111) face area ratio of not less than 5.
Claim 2
Independent Claim
115 words
A method of processing an imagewise exposed silver halide photographic material that has photographic constituent layers on a side of a support with an automatic processor, comprising: circulating a fixing solution in a fixing bath being discharged in a volume of 30-200% per minute of a capacity of said fixing bath and at a flow rate of not less than 20 m per minute, wherein said silver halide photographic material has a gelatin content of not more than 3.0 g/m 2 in said photographic constituent layers, and said photographic constituent layers comprise a silver emulsion layer which contains silver halide grains having a (100) face to (111) face area ratio of not less than 5.
Claim 3
Dependent Claim
26 words
A method according to claim 1 wherein the line speed of processing the silver halide photographic material with the automatic processor is at least 1,000 mm/min.
