ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, ELECTROSTATIC CHARGE IMAGE DEVELOPER, AND TONER CARTRIDGE

摘要

An electrostatic charge image developing toner includes toner particles including a binder resin that contains a copolymer formed by copolymerizing at least an aromatic vinyl monomer and an aliphatic unsaturated alkyl carboxylate ester, wherein a weight ratio of component M1 of the aromatic vinyl monomer and component M2 of the aliphatic unsaturated alkyl carboxylate ester in the copolymer satisfies the following expression (1), and a weight ratio of volatile component m1 of the aromatic vinyl monomer and volatile component m2 of the aliphatic unsaturated alkyl carboxylate ester, as measured by a headspace method, satisfies the following expression (2):;0.10≦MW2/(MW1+MW2)≦0.30  Expression (1);0.70≦mw2/(mw1+mw2)≦0.98  Expression (2);wherein MW1 represents the weight of M1, MW2 represents the weight of M2, mw1 represents the weight of m1, and mw2 represents the weight of m2.
