<p>PROBLEM TO BE SOLVED: To improve an electrostatic charge maintaining characteristic, an environmental stability, an image maintaining characteristic of a carrier and an electrostatic charge applying member by using a polymer, in which an acrylamide compound as a monomer constituent is contained in a principal chain while silicon is contained in a side chain, for a resin. SOLUTION: An acrylamide compound is contained in a main chain, and its amide part is located on a carrier surface. That is, in an electrophotographic carrier constructed by coating a core body particle with resin, the resin is a polymer in which an acrylamide compound as a monomer constituent is contained in a principal chain while silicon is contained in a side chain. For the acrylamide compounds, N-methylolacrylamide, N,N'-methylenebisacrylamide, N-isobutoxymethylacrylamide, N,N-dimethyl acrylamide, 2-acrylamide-2- methylopropane sulfonic acid, and the like are available, however, other similar compounds can be also used.</p> |
