| description | The present invention relates to a toner for development of electrostatic images which contains a colorant, a resin composition (P) and an ester composition (C), in which the resin composition (P) is a resin composition formed by subjecting an acid group-containing amorphous polyester-based resin (A) and an amine compound to condensation reaction, and the ester composition (C) is at least one composition selected from the group consisting of the following ester composition (CI) and ester composition (CII); and a process for producing the toner:Ester composition (CI): an ester composition containing a condensate of a carboxylic acid component (CI-ac) containing not less than 20 mol% of an aliphatic monocarboxylic acid compound having 10 to 30 carbon atoms, and an alcohol component (CI-al) containing not less than 90 mol% of a di- or higher-valent aliphatic alcohol having 2 to 14 carbon atoms; andEster composition (CII): an ester composition containing a condensate of an alcohol component (CII-al) containing not less than 20 mol% of an aliphatic monoalcohol having 10 to 30 carbon atoms, and a carboxylic acid component (CII-ac) containing not less than 90 mol% of a di- or higher-valent aliphatic carboxylic acid compound having 2 to 14 carbon atoms. |
