Abstract
When level sensors detect the fall of the levels of treatment liquids from standard levels to supply levels while a photo-developing apparatus having treatment tanks containing treatment liquids is in operation, water supply devices are activated to supply water to the standard levels in the respective treatment tanks. When the photo-developing apparatus is restarted after a suspended time, the water supply devices are activated to supply amounts of water corresponding to predicted evaporation amounts of the treatment liquids within a time set in relation to the suspended time. A sufficient development stability can be ensured by keeping the concentrations of the treatment liquids at proper values even at an operation starting point, such as when the photo-developing apparatus is restarted.
