摘要： A developing device for developing a latent image formed on an image carrier of the present invention is generally made up of a developing section and a developer storing section. The developing section includes a developer carrier for conveying a one-component type developer deposited thereon, a feeding member for feeding the developer to the developer carrier, and a conveying member for conveying the developer toward the feeding member while agitating it. The developer storing section replenishes a developer stored therein to the developing section in a direction including at least a horizontal direction component. The developing section and developer storing section are formed with a plurality of openings in the lengthwise direction such that the replenishment of developer from the developer storing section to the developing section and the return of the developer from the latter to the former are executed via the openings.

摘要： An image forming apparatus of the present invention includes a developing device including a rotatable, nonmagnetic developer carrier and a magnetic field forming device. In a developing region where the developer carrier faces an image carrier, the magnetic field forming device causes a developer made up of toner and magnetic grains to rise on the developer carrier in the form of a magnet brush. In the developing region, the magnet brush on the developer carrier is caused to move at a higher speed than the surface of the image carrier in the same direction as and in contact with the surface of the image carrier, thereby developing the latent image. The toner of the developer is magnetic toner. Flux density set up in the developing region outside of the surface of the developer carrier in a normal direction has an attenuation ratio of 50% or above.
