ABSTRACT:
A developing device for developing an electrostatic latent image formed by the electrophotographic process, etc., in which, when a developer on a non-magnetic sleeve used for developing an image is separated from the surface of this sleeve, the developer is divided into two streams, one of which is directly fed to a developer conveying device to convey the developer to a developing section for the image development, and the other of which is led to an agitating device to agitate the developer in the axial direction of the sleeve, and, after sufficient agitation, the developer stream is applied to the developer conveying device.
By the abovementioned construction, the developer from at least one of the abovementioned streams is supplied to the developer conveying device without failure, whereby a required quantity of the developer can always be supplied even when the developing device is driven at a high operating speed.
