A toner for electrostatic image development containing a resin binder and a charge control agent, wherein the resin binder contains a polyester A obtained by polycondensing a carboxylic acid component containing isophthalic acid and/or an ester thereof, and an alcohol component, and wherein the charge control agent contains an azo-iron complex represented by the formula (I): wherein each of R1 and R4, which may be identical or different, is a linear or branched alkyl group having 3 to 8 carbon atoms; each of R2, R3, R5, and R6, which may be identical or different, is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, a halogen atom, a nitro group, or a carboxyl group; and A+ is a cation. The toner for electrostatic image development is suitably used in developing latent images formed in, for example, electrophotography, an electrostatic recording method, an electrostatic printing method, or the like.
