Zusammenfassung:	PURPOSE: A development roller of an electro-photographic printer and a method for fabricating the same are provided to minimize variation of roller resistance and achieve high-quality images with low cost. CONSTITUTION: A development roller of an electro-photographic printer includes a roller body(4b) and a shaft(4a) press-fitted into the roller body(4b). The roller body(4b) is made from rubber or conductive high polymer. Rubber used for the development roller of the electro-photographic printer includes nitrile butadiene rubber, epichlorohydrin rubber or a mixture thereof. The nitrile butadiene rubber is copolymer of butadiene and acrylonitrile. The conductive material used for the development roller of the electro-photographic printer includes carbon black.
