    摘要： The invention relates to a developing roller capable of suppressing scattering of toner during a developing process and providing a further higher-quality electrophotographic image. The developing roller has a mandrel, an elastic layer provided on the circumference of the mandrel, and a surface layer provided on the circumference of the elastic layer. The surface layer contains a urethane resin serving as a binder and urethane resin particles dispersed in the binder, for forming convex portions on the surface of the surface layer. The surface of the urethane resin particle is partly covered with fine inorganic particles containing at least one element selected from silicon, titanium and aluminum and the urethane resin particles are in direct contact with the binder at the surface onto which the fine inorganic particles are not attached.
