摘要:
Magnetic composite particles suitable for a black magnetic toner have an average particle diameter of 0.06 to 1.0 µm and a coercive force value of less than 39.790 kA/m, and comprise:
(a) magnetic core particles,
(b) a coating on the surface of said magnetic core particles, comprising at least one organosilicon compound selected from:
(1) organosilane compounds obtainable from alkoxysilane compounds, and
(2) polysiloxanes or modified polysiloxanes, and
(c) an organic blue-based pigment coat which is provided on said coating (b) in an amount of from 1 to 50 parts by weight based on 100 parts by weight of said magnetic core particles.
