    摘要: A developer includes a toner container divided by a partition into first and second chambers. The first and the second chambers communicate with each other via first and second openings. A third opening is also formed in the partition for passing excessive toner from the second to the first chamber. The first chamber is provided with a first screw for transferring the toner from the first to the second opening, while the second chamber with a second screw for transferring the toner in the opposite direction. A toner scraping blade is arranged above the second screw. The toner scraped in the second chamber is led into the first chamber through the third opening. Adjusting means is provided for controlling the passage of the toner through the third opening, thereby achieving uniform toner distribution in the second chamber.

    摘要: A developing device has a vessel for holding a two-component developer composed of a toner component and a magnetic component. A magnetic roller is rotatably provided within the vessel to bring the developer to a developing zone for a development of an electrostatic latent image. An agitator also is provided within the vessel for agitating and circulating the developer to cause a triboelectrifiction between the toner component and the magnetic component and a uniform distribution of the toner component in the magnetic component. The agitator is arranged to present a uniform density mass of the developer to the magnetic roller for ensuring an even development of the latent image.
