1. A non-hydroxylic-solvent soluble silver complex comprising a reducible silver ion complexed with an α-oxy carboxylate and a 5- or 6-membered N-heteroaromatic compound,
the non-hydroxylic-solvent soluble silver complex being represented by the following formula (I):
(Ag+)a(L)b(P)c   (I)
wherein L represents the α-oxy carboxylate; P represents the 5- or 6-membered N-heteroaromatic compound; a is 1 or 2; b is 1 or 2; and c is 1, 2, 3, or 4, provided that when a is 1, b is 1, and when a is 2, b is 2,
wherein L is represented by either of the following formula (II) or formula (III), and P is selected from the group consisting of pyridine, 2-methylpyridine, 4-methylpyridine, 2,6-dimethylpyridine, 2,4,6-trimethylpyridine, 2,3-dimethylpyridine, 3,4-dimethylpyridine, 4-pyridylacetone, 3-chloropyridine, 3-fluoropyridine, oxazole, 4-methyloxazole, isoxazole, 3-methylisoxazole, pyrimidine, 2-methyl pyrimidine, pyrazine, 4-methyl pyrimidine, pyridazine, and thiazole;
