<p>PROBLEM TO BE SOLVED: To make it possible to obtain a charge control agent having excellent electrostatic charge stability and excellent moisture resistance, light resistance, heat resistance, etc., even if the agent does not contain heavy metals by incorporating a compound containing a specific compound as the charge control agent and containing potassium of a specific weight ratio of the weight of the compound in toner particles. SOLUTION: The electrostatic charge image developing toner containing a resin, coloring agents and the charge control agent contains the compound expressed by formula as the charge control agent. In addition, the compound containing the potassium at 0.01 to 10.0 wt.% by the weight of the compound expressed by the formula is included within the toner particles. In the formula, a ring A denotes a (substituted) aromatic ring; (m) denotes an integer from 1 to 3, (n) denotes an integer from 0 to 1000; R1, R2 denote hydrogen atoms, alkyl groups or aryl groups which may be different from each other; R3 denotes a hydrogen atom, alkyl group, aryl group, aralky group, alkoxy group, etc.; 1 denotes an integer from 1 to 3 and (p) denotes an integer of >=1.</p> |
