Abstract

The objectives of the present invention are attained with a release agent for toner that is obtained by grafting styrene compounds to an α-olefin polymer that conforms to the following conditions (a) and (b), wherein 70 mass % or more of the release agent is insoluble in 2-butanone when the release agent is dispersed at 25° C. into 2-butanone so that the mass ratio of the release agent to the dispersion is 15%. (a) The α-olefin polymer is to be produced by polymerization of at least one α-olefin monomer that has 16 or more to 36 or less carbon atoms. (b) The α-olefin polymer is to have a melting point between 30° C. or higher and 80° C. or lower, and has one peak temperature whose peak has the half-height width of 15° C. or less in a measurement of the melting behavior of the α-olefin polymer by means of differential scanning calorimetry.
