Abstract
PURPOSE: To surely prevent leakage of developing gas and malodorous gas to outside of the machine and reduce the use amount of ammonia and weak acids by separately providing respective gas circulating paths for the developing chamber and deodorizing chamber.
CONSTITUTION: A developing chamber 26 is in the system where the developing gas from a developing gas generating device Q is circulated through a valve W by a pump P1 and performs developing action by the ammonia gas from an aqueous ammonia solution X. On the other hand, the malodorous gas containing the developing gas leaking from the developing chamber 26 is filled in a deodorizing chamber 28 and this gas is led to a gas processing device R from a gas exhaust port 54 by way of a pump P2. There is an aqueous citric acid solution Y in the device R and the citric acid gas is led through inlet 52 to the deodorizing chamber 28. Separate provision of the respective gas circulating lines in this way prevents the increase in ammonia consumption and the use amount of weak acids through reaction of ammonia with weak acids and eliminates the leakage of the malodorous gas in the hermetic seal to the outside.
