ABSTRACT:
A toner for developing an electrostatic image is disclosed which has toner particles and hydrophobic fine titanium oxide particles. The hydrophobic fine titanium oxide particles have, in X-ray diffraction, an intensity ration Ia/Ib of 5.0.ltoreq.Ia/Ib.ltoreq.12.0 which is a ratio of maximum intensity Ia to minimum intensity Ib within the range of 2.theta.=20.0 to 40.0 deg.
