Abstract:
Toner particles of a toner contain a non-crystalline polyester resin, a crystalline polyester resin, a styrene-acrylic acid-based resin, and an ester wax. The crystalline polyester resin has a repeating unit derived from an acrylic acid-based monomer and a repeating unit derived from a styrene-based monomer. The styrene-acrylic acid-based resin has a repeating unit derived from an acrylic acid-based monomer having an amino group and a repeating unit derived from a styrene-based monomer. An amino group ratio in the styrene-acrylic acid-based resin is at least 40% and no greater than 60%. The toner has a storage elastic modulus of at least 1.00×10 5  Pa and no greater than 5.00×10 5  Pa at 90° C. The ester wax has a melting point of at least 60° C. and no higher than 80° C. A dispersion diameter of the ester wax in the toner particles is at least 500 nm and no greater than 1,000 nm.

Claim (Index 1):
An electrostatic latent image developing toner comprising a plurality of toner particles containing a non-crystalline polyester resin and an ester wax, wherein\n the toner particles further contain a crystalline polyester resin and a styrene-acrylic acid-based resin, the crystalline polyester resin has a first repeating unit derived from an acrylic acid-based monomer and a second repeating unit derived from a styrene-based monomer, the styrene-acrylic acid-based resin has a third repeating unit derived from an acrylic acid-based monomer having an amino group and a fourth repeating unit derived from a styrene-based monomer, in an FT-IR spectrum of the styrene-acrylic acid-based resin measured by an ATR method, an intensity of a peak derived from an amino group included in the third repeating unit is at least 40% and no greater than 60% of an intensity of a peak derived from an aromatic ring included in the fourth repeating unit, the toner has a storage elastic modulus of at least 1.00\u00d710 5  Pa and no greater than 5.00\u00d710 5  Pa at a temperature of 90\u00b0 C., the ester wax has a melting point of at least 60\u00b0 C. and no higher than 80\u00b0 C., and a dispersion diameter of the ester wax in the toner particles is at least 500 nm and no greater than 1,000 nm.
