摘要:
An electrostatic charge image development toner contains a plurality of toner particles. The plurality of toner particles are each formed to have resin particulates in a surface layer. The resin particulates each include a particulate core and a coating layer covering the particulate core. The particulate core contains a quaternary ammonium salt functional group-containing resin. The coating layer contains one or more resins selected from the group consisting of (meth)acrylic resins and styrene-(meth)acrylic resins.

A cyan toner comprising toner particles, each of which contains a binder resin, a compound in which a polymer portion is bound to an azo skeleton structure, and a phthalocyanine pigment serving as a colorant.
摘要:
A method for producing an electrophotographic toner comprising the step of polymerizing two or more polymerizable monomers under existence of a non-polar liquid hydrocarbon, wherein at least one of the polymerizable monomers comprises a polar group; a dynamic viscosity of the liquid hydrocarbon at 40°C is in the range of 7 - 300 mm 2 /s.
摘要:
A toner manufactured by a method of dispersing a solution or a liquid dispersion in which a composition containing a polymer having a portion reactive with an active hydrogen group is dissolved or dispersed in an organic solvent in an aqueous medium and reacting the polymer with a compound having at least one active hydrogen group. The polymer is prepared by reacting an aliphatic polyol, a polyester resin and a diisocyanate compound and has an isocyanat.e group at at least one end of the polymer.
