Abstract
An image forming apparatus includes a photoconductor, a developing electrode, at least a magnet disposed in the developing electrode, and a developer. The developing electrode is reciprocally movable against a rotation axis of the photoconductor. Thus, a setting angle of a magnetic pole of the magnet is not varied, even when the developing electrode is moved for cancelling decentering and deflection of the photoconductor and the developing electrode.
