    摘要: There is provided an electrostatic image developing toner less likely to cause image degradation even when used for a long period, by controlling CCA particles present on surfaces of toner particles and thereby keeping an amount of tribocharge generated between the toner and a magnetic carrier or the like constant. A charge control agent composition for external addition for controlling charge amount of toner particles includes: at least two types of carrier particles different in average particle size of primary particles; and a charge control agent (CCA), and an electrostatic image developing toner is constituted of a mixture of toner particles and the aforesaid charge control agent composition for external addition.
