ABSTRACT:
A toner for developing an electrostatic image is composed of toner particles each containing at least a binder resin, a colorant, and a wax. 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:
