摘要 |
A toner containing a colorant, a binder resin and a laminar inorganic mineral in which at least some of the ions present between layers are modified by organic ions and the toner is prepared by a method including dispersing or emulsifying a toner constituent mixture liquid containing the colorant, the binder resin and/or a precursor thereof, and the laminar inorganic mineral, in an aqueous medium.. The density A of the laminar inorganic mineral measured by XPS for the toner surface and the density B measured by XPS of a toner surface for the toner after mixing and kneading satisfy the following relationship: A > B.
