PROBLEM TO BE SOLVED: To stably obtain an excellent image by restraining the developer from being cracked resulting in the generation of fine powders in the case of regulating the quantity of the developer transported to a developing area in a state of holding a regulating member in press contact with the surface of the developer carrier, while preventing the fine powders of the developer from fusing on such as the surface of the developer carrier resulting in the occurrence of density unevenness or the like in the formed image, and appropriately regulating the quantity of the developer being transported to the developing area by the regulating member. SOLUTION: In this developing device provided with the developer carrier 11 holding the developer 2 on the surface while transporting to the developing area opposite to the image carrier 1, and the regulating member 16 being held in press contact with the surface of the developer carrier while regulating the quantity of the developer transported to the developing area, the surface of the developer carrier and/or the surface of the regulating member being held in press contact with the surface of the developer carrier is composed of an elastic material provided with 20 to 70 degrees rubber hardness and 400 to 1200% elongation. |
