<P>PROBLEM TO BE SOLVED: To provide a toner which ensures proper dispersibility of a black metal compound of high safety and fluidity. <P>SOLUTION: The toner for electrostatic image development is obtained, by suspending a polymerizable monomer composition containing at least a polymerizable monomer and a black colorant in an aqueous dispersion medium, and carrying out polymerization with a polymerization initiator, wherein a titanium-containing black iron oxide compound, having a saturation magnetization of 0.1-50 emu/g, an L<SP>*</SP>level of a color system of 9-15, and both a<SP>*</SP>and b<SP>*</SP>levels of -1.0 to +1.0 each, is contained as the black colorant. <P>COPYRIGHT: (C)2007,JPO&INPIT |
