    摘要: A toner for developing an electrostatic image comprises a binding resin for a toner and a charge control agent including an azo-type iron complex salt represented by the following chemical formula (1)

    (in the chemical formula (1), R 1 and R 3 are the same or different to each other and are an alkyl group having a straight chain or a branch chain of 3 to 8 carbons; R 2a , R 2b , R 4a and R 4b are the same or different to each other and are selected from the group consisting of a hydrogen atom, an alkyl group, an alkoxyl group, a halogen atom, a nitro group and a carboxyl group; A + indicates m(H + )+n(K + )+p(Na + ), which m, n and p satisfy numerical equations of m+n+p=1, 0.7≤m≤1, 0≤n≤0.3 and 0≤p≤0.3),
    wherein an average particle size thereof is 1 to 4 microns, and a specific volume resistivity thereof is ranging from 0.2X10 15 to 7X10 15 Ω·cm.
