Abstract:
An electrostatic image developing toner contains a binder resin and at least two different kinds of white pigments, wherein from about 10% by weight to about 30% by weight of the at least two kinds of white pigments is porous titanium oxide having a volume average particle diameter of from about 0.01 μm to about 1 μm, a particle size distribution (volume average particle size distribution index GSDv) of from 1.1 to 1.3 and a BET specific surface area of from about 250 m2/g to about 500 m2/g.
