发明名称 DEVELOPING DEVICE AND IMAGE FORMING APPARATUS
摘要 A developing device includes a developing-device body that includes a supply opening to which toner is supplied and a transporting member that is provided in the developing-device body and that transports the toner and a carrier while stirring the toner and the carrier. The transporting member includes a rotating shaft, a first transporting section, and a second transporting section. The first transporting section and the second transporting section are spirally formed around the rotating shaft. The number of spirals of the first transporting section is less than the number of spirals of the second transporting section. At least a portion of the first transporting section opposes the supply opening of the developing-device body. The second transporting section is formed at a portion other than the first transporting section that opposes the supply opening.
