Abstract:
A developing device, comprising a developing tank containing a developer roller for transferring by electrically adsorbing thereto a developing agent consisting of toner particles and carrier particles, wherein the developing tank is horizontally divided by a partition member into two areas, the lower area is a developing chamber containing the developer roller and the upper area is a stirring chamber containing a first and second transporting means separated by a baffle for stirring and transporting the developing agent therein, said baffle having passage holes formed therein, said stirring chamber has an inlet opening for introducing therein the developing agent regulated by a regulating member, said opening is formed between an end of the partition member and an end of the regulating member for limiting an amount of developing agent to be adsorbed by the developing roller, and the partition member has at least one port formed therein for circularly returning the developing agent from the upper stirring chamber into the lower developing chamber.
