Toner containing a laminar inorganic mineral in which part or all of the ions present between layers are modified by organic ions

摘要

A toner containing a colorant, a binder resin and a laminar inorganic mineral in which part or all of the ions present between layers are modified by organic ions. The toner can be 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 of the laminar inorganic mineral measured by XPS for the toner surface before (A) and after (B) mixing and kneading satisfies the following relationship: AB.
