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.
摘要翻译：容纳在料斗中的调色剂通过供给辊被供给到静电传送部件。在静电传送构件的致动器起作用的同时，调色剂被同时被带电输送，然后被供给到显影辊。在电场的作用下，在显影辊上形成薄层的调色剂。由于调色剂形成并且没有诸如刮刀的机械层厚度控制部件而被充电，所以作用在调色剂上的机械应力降低。

摘要： An image forming method including providing a developer including a toner and a magnetic carrier, a developer carrier configured to convey the developer deposited thereon, and magnetic field generating means fixed within the developer carrier, and forming a magnetic field which forms a magnet brush between the image carrier and the developer carrier such that the magnet brush rises, contacts the image carrier and collapses within a range in which the magnetic field is more intense than an electric field capable of separating the toner and the magnetic carrier from each other by using the magnetic field generating means. The magnetic brush rubs the image carrier to thereby develop a latent image formed on the image carrier.
