Zusammenfassung:PROBLEM TO BE SOLVED: To provide a processing method for a color photographic silver halide material with bleach-fixing solutions in which a single-part bleach-fixing precursor composition is directly replenished from an enclosed container to an LVTT processing machine. SOLUTION: In the processing method for a color-developed color photographic silver halide material, a single-part bleach-fixing precursor composition comprising at least 0.05 mol/l one or more iron-ligand complexes, at least 0.15 mol/l one or more thiosulfates as the sole photographic fixing agents, and optionally, one or more sulfites, wherein at least 50 mol% of the iron present in the composition is in the form of Fe (II), is directly delivered at a rate of at least 5.4 ml/m from the enclosed container to a processing chamber, and during or after delivering the bleach-fixing precursor composition to the processing chamber, ferrous ions in the composition are converted to ferric ions at a rate of at least 0.0002 mol/m .
