Procedure

A uniform mixture liquid was prepared by mixing 10 g of carbon black particles (average particle size: 30 nm) which were subjected to hydrophobicity-imparting treatment and 1.7 g of azobisisobutyronitrile (AIBN) (polymerization initiator) in 7 g of sodium styrenesulfonate and 130 g of styrene. In a dispersion medium comprising 1800 g of a sodium dodecyl sulfonate aqueous solution (concentration: 0.05 wt. %) and 90 g of calcium phosphate dispersed therein, the uniform mixture liquid was added. The resultant liquid was stirred at 10,000 rpm for 15 minutes by a homogenizer to prepare a suspension. Thereafter, the suspension was subjected to polymerization at 80° C. for 7 hours in a nitrogen atmosphere. After the polymerization, the resultant polymer particles were washed, followed by drying and classification to obtain black particles each comprising carbon black particle coated with (sodium styrene sulfonate-styrene) copolymer. An average particle size of the particles was about 2 microns.
