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 4):
The electrostatic latent image developing toner according to  claim 2 , wherein\n the non-crystalline polyester resin is a polymer of monomers including 1,2-propanediol, an aromatic dicarboxylic acid, and a tribasic carboxylic acid, the crystalline polyester resin is a polymer of monomers including an \u03b1,\u03c9-alkanediol, a dibasic carboxylic acid, a styrene-based monomer, and a (meth)acrylic acid alkyl ester, and the styrene-acrylic acid-based resin is a polymer of monomers including a styrene-based monomer, a (meth)acrylic acid amino alkyl ester, and a cross-linking agent.
