摘要：<p>PROBLEM TO BE SOLVED: To obtain an electrostatic charge image developing toner suitable for a recycling process to reuse the toner by incorporating a binder resin, a coloring agent and a specified charge controlling agent. SOLUTION: This toner contains at least a binder resin and a charge controlling agent comprising a zirconium compd. expressed by the formula. In the formula, R1 is a quaternary carbon, methine or methylene and may contain hetero atoms of N, S, O and P, Y is a cyclic structure coupled with satd. bonds or unsatd. bonds, each of R2 and R3 is independently an alkyl group, alkenyl group or the like, R4 is a hydrogen atom or alkyl group, each of 1 to s is an integer. The binder resin is preferably a polymer of styrene monomers, acryl monomers and methacryl monomers or a copolymer of monomers selected from these groups.</p>
