Positively-chargeable toner for developing electrostatic images, toner set and image forming method

Abstract

To provide a toner which has an excellent balance between low temperature fixability and heat-resistant storage stability, which is less likely to cause fogging, and which can form an image with excellent gloss uniformity. A positively-chargeable toner for developing electrostatic images, comprising colored resin particles which contain a binder resin, a colorant, a release agent, a release agent disperser and a charge control agent, wherein the binder resin comprises a styrene-acrylic resin and a polyester resin; wherein the release agent comprises an ester wax; and wherein the release agent disperser comprises a nonionic surfactant, and a mass of the nonionic surfactant which is present on a surface of toner particles is from 0.1 ppm to 500 ppm with respect to a mass of the toner particles.
