Toner for developing electrostatic image

Provided is a toner for developing an electrostatic image. The toner has excellent heat-resistant storage properties and crush resistance while having sufficient low temperature fixability. The toner for developing an electrostatic image 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 an aliphatic hydrocarbon group having 1 to 60 carbon atoms, an aliphatic group wherein some of carbon atoms of the aliphatic hydrocarbon group are substituted with an oxygen atom, or an aromatic hydrocarbon group optionally having the aliphatic hydrocarbon group or the aliphatic group as a substituent; and R3 and R4 each independently represent a hydrogen atom or an aliphatic hydrocarbon group.
