Toner for developing electrostatic image

A toner for developing an electrostatic image, comprising toner particles containing at least a binder resin, wherein

• the binder resin contains a copolymer prepared by copolymerizing a polymerizable monomer represented by a following general formula (2) and a polymerizable monomer represented by a following general formula (3):
• wherein in the general formula (2), R5 and R6 each independently represent an aliphatic hydrocarbon group having 3 or less 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 wherein the number of condensations is not more than 3;
• and R7 and R8 each independently represent a hydrogen atom or an aliphatic hydrocarbon group having 3 or less carbon atoms;
• in the general formula (3), R9 and R10 each independently represent an aliphatic hydrocarbon group, an aliphatic group wherein some of carbon atoms of the aliphatic hydrocarbon group are substituted with an oxygen atom, or an aromatic hydrocarbon group that may optionally have the aliphatic hydrocarbon group or the aliphatic group as a substituent;
• provided that at least one of R9 and R10 represents an aliphatic hydrocarbon group having 4 to 60 carbon atoms, or an aliphatic group wherein some of carbon atoms of the aliphatic hydrocarbon group are substituted with an oxygen atom;
• and R11 and R12 each independently represent a hydrogen atom or an aliphatic hydrocarbon group.
