Toner for developing electrostatic image

Provided is a toner for developing an electrostatic image wherein an environment variation difference in a charging ability can be controlled to be small while having sufficient low temperature fixability. The toner includes toner particles that contain at least a binder resin. The binder resin contains a polymer prepared by polymerizing a polymerizable monomer represented by a following general formula (1). In the general formula (1), R1 and R2 each independently represent a hydrogen atom, or a substituted or unsubstituted alkyl group having 1 to 2 carbon atoms; and R3 represents a hydrogen atom, or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms. X represents an oxygen atom or a single bond; Y represents a substituted or unsubstituted alkylene group having 1 to 4 carbon atoms, or a single bond; and Ar represents a substituted or unsubstituted aryl group.
