ABSTRACT:
A development roller for electrophotographic device and a method of making the development roller are disclosed. The development roller according to the present invention includes a central shaft and a roller body. The roller body is composed of an elastic polymer material as a primary material and carbon nanotubes in an amount to provide the conductivity of the roller body. According to the present invention, the development roller can exhibit a low hardness and a low resistance at the same time, produce images having high sharpness, and does not contaminate images.
