Abstract
In a developing device for supplying developer to latent images formed on an image support, a container in which the developer is contained has a sloping bottom. The container has an opening in its top so as to release the developer particles therethrough. The container houses a developer carrier, which is arranged above the sloping bottom of the container with one end located on the lower side of the sloping bottom of the container immersed in the developer particles, and with its other end located on the higher side of the sloping bottom thereof. The developer carrier has a plurality of linear electrodes arranged thereon, starting from one end to the other end, and has an electric field generator connected to these linear electrodes to successively apply voltages to these electrodes so as to generate an electric field which advances according to a lapse of time, whereby the developer particles are carried along the developer carrier, from one end to the other. That part of the developer particles which does not contribute to the developing of the image is also carried from near the opening to the other end, where it slides down by its own weight on the sloping bottom of the container to return to and near the one end again.
