Title:
MAGNETIC TONER
Document Type and Number:
WIPO Patent Application WO/2015/098923
Kind Code:
A1
Abstract:
A magnetic toner containing magnetic toner particles that contain a binding resin and a magnetic substance, and inorganic particulates, wherein the average circularity of the magnetic toner is 0.955 or greater and, when the inorganic particulates are classified, in accordance with the strength of adhesion to the magnetic tone particles, into weak-adhesion inorganic particulates, medium-adhesion inorganic particulates, and strong-adhesion inorganic particulates in increasing order of adhesion strength, the weak-adhesion inorganic particulate content, the ratio of medium-adhesion inorganic particulates to weak-adhesion inorganic particulates, and the coverage (X) of the surfaces of the magnetic toner particles by the strong-adhesion inorganic particulates are in a specific range.
