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.

A liquid developer includes a toner in which a compound having a charge-accepting functional group has been bonded to a surface of toner particles, and a carrier liquid which makes a charge density of a surface of the toner become 1 C/m.sup.2 or less when the toner is dispersed in the carrier liquid.

The present invention relates to a toner for development of electrostatic images which contains a colorant, a resin composition (P) and a resin composition (W), 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 resin composition (W) is a resin composition formed by subjecting an alcohol component (W-al), a carboxylic acid component (W-ac) and a hydrocarbon wax containing at least one functional group selected from the group consisting of a hydroxy group and a carboxy group to condensation reaction; and a process for producing the toner.
