PURPOSE:To increase a fixing speed as well as to expedite the processing of photosensitive materials by using a specific fixing solution using thiosulfate and a mesoionic compound in combination. CONSTITUTION:In contains thiosulfate of 0.5-2.0mol/liters and a mesoionic compound being expressed in a formula of 0.003-0.3mol/liters, processing takes place with a fixing solution whose value made up of dividing the mole number of a compound being expressed in the formula by that of the thiosulfate should be 0.003-0.2. In the formula, Z shows a 5 or 6 ring to be composed of a carbon atom, a nitrogen atom, an oxygen atom or the like, X<-> shows -O<->, -S<-> or -N<-> R, and R shows an alkyl group, a cycloalkyl group, an alkenyl group or the like.
