摘要： A toner for developing an electrostatic image, including a binder, a coloring agent and a charge controlling agent. When that portion of the toner which has a particle diameter of 5.04 &mgr;m or less accounts for 15-60% of the total number N of the toner, that portion of the toner which provides a number average particle diameter of 4.0 to 4.5 &mgr;m has such a content C1% by weight of the charge controlling agent that gives a ratio of C1/CT of 1.00 to 1.10, where CT is a total amount, in terms of % by weight, of the charge controlling agent in the toner. When that portion of the toner which has a particle diameter of 5.04 &mgr;m or less accounts for 15% or less of the total number N, that portion of the toner which provides a number average particle diameter of 4.2 to 4.8 &mgr;m has such a content C2% by weight of the charge controlling agent that gives a ratio of C2/CT of 1.02 to 1.15.
