Abstract
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.
