Processing of photographic silver halide photosensitive material in reduced replenishment mode

In a method for processing a photographic silver halide photosensitive material through an automatic processor having a developing tank filled with a developer and a fixing tank filled with a fixer, comprising the steps of:

• passing the photosensitive material through the developing tank for development and then through the fixing tank for fixation, and
• supplying developer and fixer replenishers to the developing and fixing tanks in amounts corresponding to the quantity of the photosensitive material processed, respectively,
• the improvement comprising
• adding at least one chelating agent to the developer and the developer replenisher,
• furnishing a developing package unit having received therein a replenisher concentrate from which the developer replenisher is prepared, and preparing the developing replenisher by diluting the replenisher concentrate in the developing package unit with water to a total volume of Pd ml,
• furnishing a fixing package unit having received therein a replenisher concentrate from which the fixer replenisher is prepared, and preparing the fixer replenisher by diluting the replenisher concentrate in the fixing package unit with water to a total volume of Pf ml,
• supplying the developer replenisher in an amount (Rep)d of up to 450 ml per unit area (1 m.sup.2) of the photosensitive material, and
• supplying the fixer replenisher in an amount (Rep)f of up to 500 ml per unit area (1 m.sup.2) of the photosensitive material,
• wherein (Rep)f/()Rep)d is equal to Pf/Pd to within.+-.5% so that the developer concentrate and fixer concentrate are consumed and replaced substantially at the same time, and (Rep)f/(Rep)d is within the range of from 0.7 to 1.5.
