PURPOSE: A developing roller and a method for manufacturing the developing roller are provided to manufacture a developing roller capable of maintaining high shape accuracy through a simple manufacturing process. CONSTITUTION: A method for manufacturing a developing roller includes a step of fabricating a roller(100) having a cylindrical outer barrel(110), an inner barrel(120) that is formed inside the outer barrel and has a hollow(130) formed in the center, and ribs(140) for connecting the outer barrel with the inner barrel, a step of cutting the roller in a predetermined length and processing the outer face of the outer barrel and the hollow of the inner barrel with accuracy, a step of fabricating a rotation axis(200), and a step of pressing the rotation axis into the hollow.
