Abstract
A toner for developing an electrostatic charge image, comprising particles containing a binder resin and a colorant, characterized in that the particles contain a fixing aid having a melting point of from to 30 to 100° C. and a surface tension of at least 39 mN/m, and the fixing aid is present with an average particle diameter of at most 1 μm in the particles, which toner can realize low-temperature fixing with a wide fixing temperature range, is excellent in fixing strength, presents little soiling onto a photoreceptor and is free from soiling in the interior of the apparatus due to electrostatic deterioration, can realize low temperature-fixing even in the case of forming a full-color image and yet, is excellent in fixing strength, provides good surface smoothness during fixing and good transparency, and provides high mechanical durability even when used in non-magnetic one component development systems.
