Abstract
The present invention is a toner for developing electrostatic charge image containing a wax derived from a plant cholesterol, an electric charge-controlling agent, a coloring agent and a binding resin. 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.
