PROBLEM TO BE SOLVED: To provide the replenisher replenishing structure of an automatic developing machine having an improved maintenance workability and also which is usable for a long period. SOLUTION: The replenisher is stored in a replenisher bag arranged in a replenisher tank 58, the tank is closed by a cap 88. The replenisher is supplied to a developing tank 22 through pipes 56 and 52 by driving a bellows pump 54, then, the replenisher is replenished to developer. Since the replenisher is stored in the replenisher bag having a tight sealing structure in such a way, the reduction of the throughput of the replenisher is prevented, because the liquid surface does not come into contact with outside air after tightly closing the bag. Thus, a plenty of replenisher can be stored, then, a replenisher replenishing interval for the replenishing tank 58 is lengthened, then the maintenance workability is improved. Besides, as for the replenisher tank 58, the external casing is provided with a prescribed rigidity, then, the replenisher bag disposed at the inside is not damaged, then, the tank 58 is usable for a long period.
