Toner for developing electrostatic charge image, electrostatic charge image developer, toner cartridge, process cartridge, and image forming apparatus

Abstract

A toner for developing an electrostatic charge image incorporates toner particles that contain binder resins including an amorphous polyester resin and a crystalline polyester resin, an ester-based release agent, and a polycondensate of a styrene-acrylic resin and a polyolefin resin. The polycondensate of styrene-acrylic and polyolefin resins has a storage modulus G′SP (70) at 70° C. of 1×104 Pa or more and 1×107 Pa or less and a storage modulus G′SP (90) at 90° C. of 1×103 Pa or more and 1×106 Pa or less in dynamic rheometry. The toner particles have a storage modulus G′T (70) at 70° C. of 1×104 Pa or more and 1×106 Pa or less and a storage modulus G′T (90) at 90° C. of 1×103 Pa or more and 1×105 Pa or less in dynamic rheometry.
