Abstract
A developing roller is made up of a magnet member and a sleeve surrounding the magnet member. A sophisticated magnetic characteristic including a repulsive pole can be easily formed on the surface of the sleeve. The repulsive pole causes a developer to be sharply released from the surface of the sleeve. A developing device including the developing roller is also disclosed.
