ABSTRACT:
The present invention relates to a toner for electrostatic image development, comprising a crystalline ester compound synthesized by polymerizing a carboxylic acid component with an alcohol component, a non-crystalline resin, a colorant and a releasing agent, wherein the weight-average molecular weight of the crystalline ester compound is 5000 or less, and the number of carbon atoms in at least one component selected from the carboxylic acid component and the alcohol component is 10 or more.
