Abstract:
A toner for developing an electrostatic image, comprising: toner particles each containing at least a binder resin, a colorant, and a wax having a branched structure and a methyl group at terminals of chains of the wax;wherein the wax satisfies conditions of:(a) showing a maximum heat-absorption peak in a region of 50-130.degree. C. on temperature increase on a DSC (differential scanning calorimeter) curve, and(b) giving a .sup.13 C-NMR (nuclear magnetic resonance) spectrum showing a total peak area S in a range of 0-50 ppm, a total peak area S1 in a range of 36-42 ppm and a total peak area S2 in a range of 10-17 ppm satisfying:1.0.ltoreq.(S1/S).times.100.ltoreq.10, 1.5.ltoreq.(S2/S).times.100.ltoreq.15, and S1<S2.
