Carrier for electrophotography, two-component type developer for developing electrostatic images, process for producing carrier for electrophotography, and image forming method |
| abstract |
1. A carrier for electrophotography comprises carrier core particles and a coating resin material. The surfaces of the carrier core particles are each coated with the coating resin material and the coating resin material comprises a resin and a quaternary ammonium salt represented by the following formula:n wherein R₁, R₂, R₃ and R₄ each represent an alkyl group, an aryl group or an aralkyl group and R₁, R₂, R₃ and R₄ may be the same or different from each other; and A represents an organic anion, an isopolyacid ion or a heteropolyacid ion. |
