Abstract
A method of detecting the quantity of replenishing solution remaining in a replenishing-solution tank in an automatic developing machine, which tank stores a replenishing solution to be supplied to a processing tank for processing a light sensitive material, comprises the steps of subtracting the quantity of replenishing solution supplied to the processing tank from a storage quantity representing the amount of replenishing solution stored in the replenishing-solution tank; and detecting the value of the subtraction as the quantity of replenishing solution remaining in the replenishing-solution tank. Accordingly, an operator can detect the remaining quantity of replenishing solution without the need to visually inspect the replenishing-solution tank.
