Document Type and Number:
WIPO Patent Application WO/2022/004607
Kind Code:
A1
Abstract:
Provided is a toner for development of electrostatic images that comprises color resin particles containing a binder resin, a color agent, a charge control agent, and a mold release agent, wherein the storage modulus G'(60) of the color resin particles at 60°C, obtained by a dynamic viscoelasticity measurement, is 1.0×108 to 5.0×108 Pa, the storage modulus G'(100) at 100°C is 8.0×104 to 2.3×105 Pa, and the storage modulus G'(150) at 150°C is 1.4×104 to 3.0×104 Pa.
