<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner having good environmental stability of the charged state, good hot storage resistance and fixing strength. SOLUTION: The electrostatic charge image developing toner contains toner particles containing at least a binder resin (A), a polymer (B) having a weight average molecular weight of 1,000-3,000 and a weight average molecular weight to number average molecular weight ratio of <=2.0 and a colorant and satisfies the relations of (1) a>1.0 and a>b and/or (2) a>b and c<aX.b1-X [where (a) is the grindability index of the binder resin (A); (b) is the grindability index of the polymer (B); (c) is the grindability index of a toner composition obtained by kneading and cooling toner materials; and X is the weight proportion of the binder resin (A) to the total amount of the binder resin(A) and the polymer (B)].</p> |
