Antioxidizing manner of the developer in the film automatic development machine being the manner which prevents the degradation in efficiency with the oxidation of the developer in the film automatic

摘要

PROBLEM TO BE SOLVED: To provide a new method by which a deterioration in developer caused by oxidation is suppressed without the use of an additive, replenishing of developer and the use of a floating plate and to provide a new developing device to which the method is applied.;SOLUTION: In the method for preventing a deterioration in performance of developer caused by oxidation in a film automatic developing device, minus ions are supplied to at least either the surface of the developer or into the developer. An automatic film developing device is provided with a minus ion discharging section 12 used to discharge minus ions into a space inside a developing device chamber 16 that includes a developing pail 4 into which the developer is filled. Thus, the deterioration in the developer caused by oxidation is easily prevented without the use of an additive or the like.;COPYRIGHT: (C)2004,JPO
