摘要：
A liquid developing agent includes a toner particle having a nuclear particle and a covering layer containing a wax, provided on the surface of the nuclear particle in which the wax has at least one of polar groups and aromatic substituent groups, is substantially insoluble in an electric insulation solvent at room temperature, has a melting point below a boiling point of the electric insulation solvent, and is dissolved in the insulation solvent at a temperature higher than the melting point.
