Abstract: A developing device includes a developer container, a developing unit, a developer outlet and a replenishment developer inlet. The developer container contains a developer composed of a toner and a first carrier. The developing unit develops an electrostatic latent image on an image carrier using the developer. The developer outlet discharges the developer. The replenishment developer inlet supplies a replenishment developer to the developer container. The replenishment developer includes a second carrier. A ratio of a poured bulk density of the second carrier to a poured bulk density of the first carrier ranges from 0.60 to 0.95.
