ABSTRACT:
A developing device develops an electrostatic latent image formed on a photosensitive drum by using a magnetic developer. The developing device comprises a body frame having a storage section storing the magnetic developer, a developing roller disposed inside the body frame and including a first section facing the storage section and a second section facing the photosensitive drum, for supplying the magnetic developer in the storage section to the second section through the shift of a magnetic field, whereby the magnetic developer supplied to the second section by the developing roller is attracted to the electrostatic latent image on the photosensitive drum, and an intermediate plate provided in the frame body under the developing roller to bear thereon the magnetic developer dropped from the developing roller.
