PROBLEM TO BE SOLVED: To provide processing solution replenishing equipment in which the picture quality of the picture of a photosensitive material to be subjected to development is improved by improving the accuracy of development processing by accurately replenishing a development processing solution and retaining an error in cumulative discharge amount within a specified range. SOLUTION: The measuring discharge amount and the measurement requiring time per cycle of a replenishing pump 42 are measured by means of a measuring cylinder 44, a rotary encoder S11a, a bellows expansion sensor S12a, and a timer (not shown) or the like to correct the setting replenishment time and the frequency of setting replenishment of the replenishing pump 42. The discharge amount per cycle of the replenishing pump 42 is used as a reference. Applying multiple of integer to the discharge amount obtains approximation with respect to an estimated replenishment amount. Replenishment is done by the integer cycle portion. The resulting difference is carried over for the next replenishment. Arithmetic processing, using the difference as the next estimated replenishment amount is done. In performing the arithmetic processing, the fraction of the sum of the estimated replenishment amount and the difference is previously raised/omitted/rounded to perform the arithmetic processing.
