    摘要: The developer producing equipment of the present invention is equipped with a preparation tank to which a developer stock solution and pure water are supplied, and in which these ingredients are agitated, and a leveling tank which is connected to this preparation tank. The leveling tank is connected via piping to working equipment in which electronic circuits are formed. Furthermore, the preparation tank and leveling tank have first and second alkali concentration measuring means for measuring the alkali concentrations of the alkali type developer inside the respective tanks. In the preparation tank, either the amount of developer stock solution that is supplied to the tank or the amount of pure water that is supplied to the tank, or both, are adjusted on the basis of the measured value obtained by the first alkali concentration measuring means, so that an alkali type developer is prepared. This alkali type developer is fed into the leveling tank, where the alkali concentration is evened out, after which the alkali type developer is fed into the working equipment via piping.
