The solution having bleaching capability comprises a ferric complex salt of a compound represented by the following formula A: ##STR1## wherein A.sub.1, A.sub.2, A.sub.3 and A.sub.4 are independently a --CH.sub.2 OH group, a --PO.sub.3 M.sub.2 group or a --COOM group, which may be the same or different; M is a cation: and X is an alkylene group having 2 to 6 carbon atoms or a --(B.sub.1 O).sub.n --B.sub.2 -- group, in which is an integer of 1 to 8, B.sub.1 and B.sub.2 are independently an alkylene group having 1 to 5 carbon atoms, which may be the same or different. The solution can be used as a bleaching solution or bleach-fixing solution for color photographic material. The solution may further be used as a reducing solution for reducing an image formed on a photographic light-sensitive material.

Processing method for silver halide color photographic light-sensitive

An apparatus for processing a silver halide photographic material with a processing solution comprises a guide passage constructing member provided between a solid agent replenishing device and a processing solution in a tank. The guide passage constructing member forms a guide passage enclosed with an inner wall surface thereof so as to guide a dropped solid processing agent along the enclosed guide passage into the processing solution. The guide passage constructing member is so arranged that a part of the enclosed guide passage is inclined to a horizontal plane and has a ventilating opening to communicate between an enclosed space in the enclosed guide passage and an outer space of the enclosed guide passage.
