ABSTRACT:
A black pigment powder having a low value of magnetization according to the present invention is characterized in that it consists of a composite oxide containing Fe2TiO4as a main component, wherein the total amount of Fe (II) and Fe (III) to Ti is from 150 to 300 atomic %, in such an amount that the amount of Fe (II) to the total amount of Fe (II) and Fe (III) is 0.50 or more, and that the L value of a coating according to the Hoover-type muller method is 9.0 or less. It is employed to produce a toner composition, a coating composition, a resin composition, a cosmetic material and the like.
