<P>PROBLEM TO BE SOLVED: To provide a toner excellent in low temperature fixability as well as excellent in charging stability and environmental stability. <P>SOLUTION: The toner comprises: at least toner particles produced in an aqueous medium; and an inorganic fine powder. The toner particles contain at least a binder resin, a colorant, a release agent, an ionic surfactant and a nonionic surfactant. The binder resin contains a crystalline polyester obtained by condensation polymerization of an aliphatic diol and an aliphatic dicarboxylic acid. The content of the crystalline polyester included in the toner is 2 to 50 parts by mass with respect to 100 parts by mass of the toner particles. The content (A) of the ionic surfactant included in the toner is 10 ppm or more and 1000 ppm or less; and the content (B) of the nonionic surfactant included in the toner is 100 ppm or more and 5000 ppm or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
