Toner for use in electrophotography and method of producing the same
 A toner for use in electrophotography has toner particles, each toner particle containing a resin, a colorant, a fluidity-imparting agent and a volatile organic component which is in an amount of 100 ppm or less per unit amount of the toner particles, and having an average spherical degree in a range of 100 to 150. In addition, the above-mentioned toner is produced by preparing primary particles, each particle including a resin and a colorant, depositing a fluidity-imparting agent on the surface of the primary particles, dispersing the fluidity-imparting agent deposited primary particles in a liquid containing a dispersant, in which liquid the resin is insoluble, thereby preparing a dispersion of the primary particles, heating the dispersion with stirring, and cooling the dispersion, thereby obtaining toner particles for use in the toner.
