Patent ID: 7214459

Claim:
A toner for developing electrostatic images comprising toner mother particles, and an external additive, wherein: the average of shape factors SF 1 of the toner mother particles represented by the following Formula (1) is 140 or less; the external additive contains higher alcohol particles having a volume-average particle diameter of 1 to 12 μm; and the content of the higher alcohol particles having a diameter equal to or less than the volume-average particle diameter of the toner mother particles is in a range of 0.15 to 2.5 parts by weight with respect to 100 parts by weight of the toner mother particles: SF 1=( L 2 /A )×(π/4)×100 Formula (1) wherein L represents the maximum length of each toner mother particle; and A represents the projected area of each toner mother particle.
