<P>PROBLEM TO BE SOLVED: To provide toner which is hardly flocculated and allows fixing at a low temperature, and also to provide a two-component developer containing the toner, and a developing device using the two-component developer. <P>SOLUTION: The toner contains a first toner particle group and a second toner particle group. A volume average particle size of the first toner particle group is smaller than that of the second toner particle group. Only toner particles constituting the second toner particle group, out of toner particles constituting the first toner particle group and toner particles constituting the second toner particles group, contain a crystalline polyester resin. The two-component developer containing this toner is charged in the developing device to perform development. <P>COPYRIGHT: (C)2011,JPO&INPIT |
