<p>PROBLEM TO BE SOLVED: To provide the electrostatic latent image developing toner superior in rising of charge and charge stability for a long period. SOLUTION: The electrostatic latent image developing toner contains a binder resin and a colorant and a charge controller comprising a specified azo type metal complex and a zirconium compound represented by formula in which R1 is a quaternary carbon, methyne, or methylene group opitionally substituted by an N, S, O, or P atom; Y is a cyclic structure combined through saturated or unsaturated bond; each of R2 and R3 is an alkyl or alkenyl group or the like; R4 is an H atom or an alkyl group; and each of (l), (m), (v), (n), (o), (p), (q), and (s) is an integer of 0-12, 1-20, 1-20, 0-20, 0-4; 0-4; 0-3, and 0-20, respectively.</p> |
