A developing roller and a developing device are provided to enable a satisfactory developing operation. In order to accomplish this object, a roller main body of the developing roller is made of a roller base material containing acrylonitrile-butadiene rubber as a main component, and an adherence preventing coating layer is formed on the outer circumferential surface of the roller main body, thereby preventing the adherence of developer to the roller main body. Particularly, by setting the friction coefficient of the coating layer within a range of 0.5 to 0.95 inclusive and/or the glossiness thereof within a range of 4.5 to 8 inclusive, an occurrence of any of negative ghost, positive ghost and background fogging is prevented or suppressed to a level where no problem is presented in practical use.
