Abstract
A developing solution includes at least one of a compound represented by formula (I) and a compound represented by formula (II) and being at pH 2 to 10: wherein, in the formula (I) and (II), R1 to R10 each independently represent one of a hydrogen atom an an alkyl group; “1” represents an integer of 1 to 3; and X1 and X2 each independently represent one of a sulfonate salt, a sulfate monoester salt, a carboxylate salt and a phosphate salt, provided that the total sum of the carbon atoms in R1 to R5 and the total sum of the carbon atoms in R6 to R10, respectively is 3 or more.
