An image forming apparatus having a vibration reducing member is provided. The image forming apparatus includes a photosensitive member, a developing roller, an axis of the developing roller, and a gear train for driving the developing roller. Accordingly, the quality of print image is improved by providing the vibration reducing member in which the natural frequency in the rotation direction of the developing roller is less than the exciting frequency in the direction of the developing roller.
