Abstract:
There is provided a conductive roller for electrophotographic equipment in which a shaft made of core metal has excellent rust resistance. The conductive roller includes a shaft made of core metal, a protective layer formed on the outer periphery of the shaft, and a conductive rubber elastic layer formed on the outer periphery of the protective layer. In a conductive roller for electrophotographic equipment, the conductive rubber elastic layer contains a rubber containing halogen atoms, and the protective layer is formed of a crosslinked material of a composition containing a material obtained by melting and mixing the following components (a) to (c): (a) a polyfunctional maleimide compound having two or more maleimide groups; (b) a benzoxazine compound; and (c) an epoxy resin.
