Abstract: Disclosed are a toner for development of electrostatic image, comprising as the main component a resin obtained by allowing a polymer containing a polymer component with low molecular weight and a polymer component with high molecular weight, at least the polymer component with low molecular weight containing a carboxylic acid component, to react with a polyvalent metal compound, and a method of fixing a toner image employing the toner described above.According to the present invention, there can be provided a toner for development of electrostatic image which has more improved fixability without lowering the anti-off-set property already improved, and also which can be prepared with good reproducibility without causing gelation to occur although the metal compound may be formulated therein, and can be improved in fixability without making charging characteristics unstable and at the same time without bringing about lowering in anti-off-set property, and thus an excellent toner image can be fixed.
