ABSTRACT:
A developing device including a developing agent container for storing a developing agent composed of toner particles and magnetic carrier particles, a toner carrier for carrying and conveying the toner particles to supply the toner particles to an image carrier for carrying an electrostatic image, and a developing agent regulating rotary member, disposed adjacent the toner carrier with a gap therebetween, for forming a brush of the magnetic carrier particles by a magnetic force between itself and the toner carrier. The regulating rotary member allows only the toner to pass therethrough without substantially allowing passage of the carrier.
