Abstract

A toner for developing electrostatic images having a uniform composition and uniform performances over varying sizes of toner particles is constituted by (a) a binder resin, (b) a long-chain alkyl compound and (c) an azo-type iron complex. The long-chain alkyl compound is represented by the following formula (1), (2) or (3):
CH3~CH2~CH2OH (1), (see formula I) CH3~CH2~CH2COOH (3), wherein x and y independently denote an average value in the range of 35 - 150; z denotes an average value in the range of 1 - 5, and R denotes H or an alkyl group having 1 - 10 carbon atoms. The azo-type iron complex compound is represented by the following formula (4);
(see formula II) wherein X1 and X2 independently denote hydrogen atom, lower alkyl group, lower alkoxy group, nitro group or halogen atom; m and m' denote an integer of 1 - 3; R1 and R3 independently denote hydrogen atom, C1-18 alkyl or alkenyl, sufonamide, mesyl, sulfonic acid group, carboxy ester group, hydroxy, C1-18 alkoxy, acetylamino, benzoylamino or halogen atom; n and n' denote an integer of 1 - 3; R2 and R4 denote hydrogen atom or nitro group; and A+ denotes a cation including 75 - 98 mol. % of ammonium ion and another ion selected from the group consisting of hydrogen ion, sodium ion, potassium iron and mixtures thereof.
