    摘要: An image forming apparatus including an image bearing member; and a developing device including a developer bearing member, a developer containing portion, a developer supplying passage supplying the developer to the developer bearing member while feeding the developer in a direction, and a developer agitating passage feeding a mixture of the developer fed through the developer supplying passage without used for developing, and the developer used for developing, in the opposite direction. The developer supplying passage, and developer agitating passage are separated from each other except for at least both the end portions. The developer includes a toner and a carrier having a cover layer thereon, which includes a binder resin and a particulate material. The ratio of the volume average particle diameter of the particulate material to the average thickness of the resinous portion of the cover layer is greater than 1 and less than 10.
