ABSTRACT:
A toner for electrostatic image development, containing a resin binder containing a polyester having monomer units wherein at least one monomer is selected from the group consisting of fumaric acid and maleic acid, including mixtures thereof; a colorant; and a charge control agent containing a negatively chargeable charge control agent and a positively chargeable charge control agent, wherein the unreacted monomers of fumaric acid, maleic acid or both fumaric acid and maleic acid are contained in the toner in an amount of 0.20% by weight or less. The toner for electrostatic image development of the present invention may be used for the development of a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method or the like.
