PURPOSE:To provide a tank equipped with pipes with temperature controlling function and to make a liquid temperature in the tank always coincides with the liquid temperature of a tank provided with a temperature controlling function by circulating the liquid in a chemical tank provided with a temperature controlling function through the pipe distributed to other chemical tanks. CONSTITUTION:Temperature control devices 160A, 160B are connected to two tank, i.e. a color developing tank 110 and a bleaching and fixing device 120, in an automatic developing device. A circulation pipe 193B on the discharge side of a circulation pump 191B connected to the tank 120 is is returned to the tank 120 through the 1st stable tank 130 adjacent to the tank 120. Similarly, a circulation pipe 194B connected to the discharge side of a circulation pump 191C connected to the tank 130 is also returned to the tank 130 through the 2nd stable tank 140 adjacent to the tank 130. The 1st and 2nd tanks 130, 140 passed by the circulation pipes 193B, 194B are provided with the temperature controlling function so that liquid temperature in the tanks 130, 140 is made always to coincide with that of the tank 120.
