Electrostatic image development toner

A process for producing a toner for development of electrostatic images, the process comprising:

• 1:
• subjecting an acid group-containing amorphous polyester-based resin (A) and an amine compound to condensation reaction to obtain a resin composition (P);
• and
• 2:
• melt-kneading toner raw materials comprising the resin composition (P) obtained in 1, a colorant, a releasing agent, and an ester composition (C),
• wherein the ester composition (C) is at least one composition selected from the group consisting of the following ester composition (CI) and ester composition (CII):
• ester composition (CI):
• an ester composition comprising a condensate of a carboxylic acid component (CI-ac) comprising not less than 20 mol % of an aliphatic monocarboxylic acid compound comprising not less than 10 and not more than 30 carbon atoms, and an alcohol component (CI-al) comprising not less than 90 mol % of a di- or higher-valent aliphatic alcohol comprising not less than 2 and not more than 14 carbon atoms;
• and
• ester composition (CII):
• an ester composition comprising a condensate of an alcohol component (CII-al) comprising not less than 20 mol % of an aliphatic monoalcohol comprising not less than 10 and not more than 30 carbon atoms, and a carboxylic acid component (CII-ac) comprising not less than 90 mol % of a di- or higher-valent aliphatic carboxylic acid compound comprising not less than 2 and not more than 14 carbon atoms.
