A non magnetic toner comprises toner particles each containing at least a binder resin, a colorant and a wax component. The toner further comprises an inorganic fine powder. A storage elastic modulus at 110° C. (G′ 110 ) of the non magnetic toner is in a range of 2.00×10 4 to 2.00×10 5 dN/m 2 . A storage elastic modulus at 150° C. (G′ 150 ) of the non magnetic toner is in a range of 3.00×10 3 to 2.00×10 4 dN/m 2 . The toner particles are obtained by dispersing a polymerizable monomer composition containing polymerizable monomers, the colorant, the wax component and a low-molecular weight polymer into an aqueous medium, granulating the dispersed polymerizable monomer composition, and polymerizing the polymerizable monomers in granulated particles. The low-molecular weight polymer has a weight average molecular weight (Mw) measured by means of gel permeation chromatography (GPC) in a range of 2000 to 5000. |
