An image forming apparatus includes an image forming unit having an image carrier, a developing agent container for holding a developing agent, and a developing agent supplier for supplying the developing agent from the developing agent container to the image carrier. A controller determines the amount of use of the image forming unit. A shaking mechanism shakes the image forming unit from time to time, at intervals determined by the controller according to the amount of use of the image forming unit. The shaking loosens the developing agent so as to maintain its fluidity, thereby avoiding faint image formation. |
