1. The reduction potentials were measured using p-aminodiethylaniline and they were higher than those of metol or hydroquinone solutions.
2. Influence of addition of sodium carbonate, sodium sulfite and hydroxylamine sulfate was studied and potential decreases were observed by addition of sulfite and hydroxylamine.
3. Potential decreases of p-aminodiethylaniline were affirmed in the presence of color forming reagents (couplers). It is fairly probable that the amount of oxidized form of developer may be decreased by addition of sodium sulfite, hydroxylamine or couplers.
4. It is found that the coupling ability of compounds to form dye with developer can easily be detected by potential measurements of developer solutions.
