A developing device configured to form toner cloud without making toner particles adhere to the electrostatic transport substrate having electrodes. By applying periodical voltages to electrodes, electrically charged toner particles float on the electrostatic transport substrate. Also, a rotatable toner transporter designed to carry toner particles floating on the electrostatic transport substrate. Also, a two-component developer bearer including a sleeve with magnets on which the two-component developer is borne. The two-component developer borne on the sleeve is sent to the toner transporter by rotation of the sleeve. There, toner particles are transported to the toner transporter because of the electric bias applied between the two-component developer bearer and the toner transporter. Toner particles electrically floating on the toner transporter are sent to the photoconductor for development.
