A storage elastic modulus at 110° C. (G′110) of the non magnetic toner is in a range of 2.00×104 to 2.00×105 dN/m2. A storage elastic modulus at 150° C. (G′150) of the non magnetic toner is in a range of 3.00×103 to 2.00×104 dN/m2. 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.
