ABSTRACT:
A method of supplying a replenishing solution to the processing tank incorporated in an automatic developing machine in which a photosensitive material is processed. In the method, a less active replenishing solution is first supplied to the processing tank at the commencement of the present processing operation of the automatic developing machine prior to our in the course of the processing of the photosensitive material, the less active replenishing solution compensating for the deterioration of a developer due to air during the preceding operating period and the subsequent stop period of the automatic developing machine. A normally active replenishing solution is then supplied to the processing tank after completion of the supply of the less active replenishing solution, the normally active replenishing solution compensating for the deterioration of the developer due to the processing of the photosensitive material. Accordingly, since these replenishing solutions are supplied in this manner, the photosensitive material can be stably developed.
