ABSTRACT:
A developing device for supplying toner particles to an electrostatic latent image support member having an electrostatic latent image formed thereon to develop the electrostatic latent image comprises a toner conveying member for conveying and supplying the toner particles to the electrostatic latent image support member having the electrostatic latent image formed thereon, a power supply for applying a predetermined developing bias voltage to said toner conveying member, and charge movement preventing means connected between the toner conveying member and the power supply for preventing charges induced in the toner conveying member as the electrostatic latent image is developed from flowing toward the power supply.
