Title:
TONER
Document Type and Number:
WIPO Patent Application WO/2010/021048
Kind Code:
A1
Abstract:
In the image formation method for fixing an unfixed toner image in a non-contact manner by the high-frequency magnetic field-induced heating, a toner is used, which is composed of a core particle comprising a thermoplastic polymer material and multiple superparamagnetic microparticles adhered on the surface of the core particle and each having a particle diameter of smaller than 100 nm, wherein the superparamagnetic microparticles each having a particle diameter of smaller than 100 nm do not contact with other superparamagnetic microparticles. It becomes possible to prevent the scattering of the toner caused by the influence of the magnetic field, and to form a high-quality image.
