Developer replenishers having buffer controlled high pH and high potassium/sodium weight ratio are effective at low-replenishment rates; for example, developer replenishers having a pH of 10.5 to 11 containing a potassium/sodium weight ratio of at least 5.4/1,p-phenylenediamine developing agent and benzyl alcohol in weight ratio of between about 1/1.5 and 1/2 and sulfite are especially effective. Such replenishers are advantageously prepared from kits comprising at least two solutions, one a buffered aqueous alkaline solution containing alkali metal ions in a high potassium/sodium weight ratio and another an aqueous solution having low pH and containing p-phenylenediamine developing agent in high concentration. The replenishers are utilized in conjunction with the processing of imagewise exposed, multilayer, incorporated coupler, silver halide sensitized, color photographic film materials.
