PURPOSE: To simplify a water storage tank of the sensitized material treating device.
CONSTITUTION: In a developing part 14, the tip of a piping 58 connected to external water service is opened in an auxiliary tank 18. In a bottom plate 18A of the auxiliary tank, one end of a piping 134 penetrates and is opened so as to be opposed to the opening of the piping 58, so that water from the piping 58 flows in. The piping 134 is connected to a feed water pump 130 through an expanded diameter tube 128, so that water of a prescribed quantity can be stored between the tube and the feed water pump 130. The feed water pump 130 is opened to a replenishing cylinder 132, and in a state that an operation of the feed water pump 130 is stopped, water from the piping 58 is stored in the expanded diameter tube, and water overflowing the piping 134 flows as developing water into the developing part, and water in the expanded diameter tube is supplied to the replenishing cylinder 132 by an operation of the feed water pump 130.
