Abstract
A processing method of a silver halide light sensitive photographic material by the use of an automatic processor is disclosed, in which a developing solution contains a developing agent represented by the formula described below and a developer replenishing solution having activity lower than that of a developing solution used at the time of starting processing is replenished within a predetermined amount to be replenished per unit time, and when the replenished amount of the developer replenishing solution has exceeded the predetermined amount to be replenished per unit time, a developer replenishing solution having higher activity is replenished.
Claims6
In a method for processing a silver halide light sensitive photographic material comprising the steps of:
- (a) developing an exposed photographic material with a developer solution,
- (b) fixing the developed photographic material with a fixer solution, and
- (c) washing with water or stabilizing with a stabilizer solution the fixed photographic material,
- wherein the photographic material comprises a support and a silver halide emulsion layer, and
- herein in step (a), a first developer replenishing solution exhibiting activity lower than that of a developer mother solution used at the start of processing is replenished, a first amount to be replenished with the first developer replenishing solution is predetermined in terms of volume per prescribed unit time, so that in case that the replenished amount of the first developer replenishing solution exceeds the first amount within the prescribed unit time, a second developer replenishing solution exhibiting activity higher than that of the first developer replenishing solution is replenished, the improvement comprising with respect to sludge formation after many days in the above method and the developer solution comprises a compound represented by formula (2) as a developing agent in an amount of 0.1 to 1.0. mol/l,
- wherein R1 and R2 are each an alkyl group, an amine group, an alkoxy group, or an alkylthio group, provided that R1 and R2 may combine together with each other to form a ring;
- k is 0 or 1;
- when k is 1, X is —CO— or —CS—;
- and M1 and M2 are each a hydrogen atom or an alkali metal atom.
