Claim:
1. A toner for developing an electrostatic latent image, comprising: toner particles including a binder resin, a colorant, and a release agent, the binding resin including a vinyl resin and a non-crystalline polyester resin, wherein, the toner particles include a matrix phase composed of a vinyl resin, and domain phases composed of a non-crystalline polyester resin dispersed in the matrix phase, a number-average domain diameter of the domain phases composed of the non-crystalline polyester resin is 30 to 150 nm, and the toner satisfies the following Requirement (1): where when “r” is defined as an average radius of a cross-section, having a maximum area, of the toner particle, “a” represents a total area, in the cross-section, of the domain phases composed of the non-crystalline polyester resin present in a surface layer area having a distance of r/5 inwardly in a radial direction from a surface of the toner particle, and “b” represents a total area, in the cross-section, of the domain phases composed of the non-crystalline polyester resin present in areas other than the surface layer area.
