ABSTRACT:
A developing apparatus includes a control electrode assembly provided in an upstream portion of a developing area of a developing sleeve that is opposed to an image retainer. The control electrode assembly is provided with an insulating member so that it can be located close to the developing sleeve or it can be contacted with the developing sleeve. An end portion of the control electrode is protruded onto a downstream side with respect to an end portion of the insulating member so that a toner cloud can be generated immediately before the developing area.
