摘要： A developing device capable of obviating carrier deposition on an image carrier and uniformly distributing toner on a developer carrier is disclosed. A developer deposited on the developer carrier and moved away from a metering member rises in the form of a magnet brush, falls down, and again rises in accordance with the movement of the developer carrier. The toner of the developer is efficiently agitated in the axial direction of the developer carrier in a narrow zone between the first metering member and a developing zone.

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.
摘要翻译：本发明的图像形成装置包括显影装置，其包括可旋转的非磁性显影剂载体和磁场形成装置。在显影剂载体面向图像载体的显影区域中，磁场形成装置使得由调色剂和磁性颗粒组成的显影剂以磁刷的形式在显影剂载体上升高。在显影区域中，使显影剂载体上的磁刷以与图像载体的表面相同的速度在与图像载体的表面相同的方向上移动，从而显影潜像。显影剂的调色剂是磁性调色剂。在正常方向的显影剂载体表面之外的显影区域中形成的通量密度具有50％以上的衰减率。

摘要： A toner contained in a hopper is fed to an electrostatic conveyance member by a supply roller. With an actuator of the electrostatic conveyance member functioning, the toner is conveyed while being electrically charged at the same time, and is then supplied to a development roller. A thin layer of toner is formed on the development roller under the effect of an electric field. Since the toner is formed and charged without a mechanical layer thickness controlling member such as a doctor blade, mechanical stress acting on the toner is reduced.
