The toner is suited for use in the electromagnetic induction-heated fixing system which is capable of heating the heating member up to a predetermined fixing temperature in a short period of time, makes it possible to maintain images free of irregular luster or fouling for extended periods of time and is, further, suited for being fixed at a low temperature.

Abstract: A process for producing a charge control agent comprising an azo-based iron complex salt compound as an effective component, comprises: synthesizing a monoazo compound through diazotization coupling; and ironing the monoazo compound by using an ironizing agent such as ferric chloride to produce an azo-based iron complex salt compound represented by the following formula. The ironization reaction of the monoazo compound is carried out while pH is kept at 7.0 to 8.0. Since the above azo-based iron complex salt compound having high purity can be obtained at a high yield, it can be used as a charge control agent directly and a special purification step can be eliminated, thereby making it possible to greatly cut the production cost.
