ABSTRACT:
A developing device for developing an electrostatic latent image with a two-component developer comprises a developer container (46) including a developer-accumulating chamber (50), and a developer-agitating chamber (56) provided above the developer-accumulating chamber. A communication passage (64) is provided between the developer-agitating chamber and the developer-accumulating chamber, and is opened to the developer-agitating chamber to define an overflow opening for the developer. The device also comprises a developer-carrying body (48) provided in the developer-accumulating chamber of the developer container, and the developer-carrying body is exposed to face an electrostatic latent image carrying body, and brings the developer from the developer-accumulating chamber to a facing zone therebetween for development of an electrostatic latent image formed on the electrostatic latent image carrying body. The device further comprises a developer-lifting means (68, 68', 70) for lifting the developer, brought to the facing zone by the developer-carrying body, to the developer-agitating chamber of the developer container, and a developer-agitating means (58) for agitating the developer in the developer-agitating chamber of the developer container, a part of the developer agitated by the developer-agitating means being fed to the developer-accumulating chamber through the overflow opening and the communication passage.
