A toner for developing an electrostatic image is composed of toner particles containing at least a binder resin, a colorant and a wax composition. The wax composition comprises an ester wax (1) having a long-chain alkyl group, and a wax (2). The wax (2) shows a maximum heat-absorption peak in a range of 40-130 DEG C. on temperature increase on a DSC (differential scanning calorimeter) curve, and gives a 13C-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</=(S1/S)x100</=10, 1.5</=(S2/S)x100</=15, and S1<S2. The toner particles contain A wt. parts of the ester wax (1), B wt. parts of the wax (2) and C wt. parts of the colorant, respectively per 100 wt. parts of the binder resin, satisfying: 3</=A</=30, 0.2</=B</=10, 4</=A+B</=40, 0.02</=B/A</=0.5, and 0.02</=B/C</=2.
