Abstract:
A developing device for an image forming apparatus, comprising:a developer carrier configured to develop a latent image formed on an image carrier by depositing toner to thereby produce a corresponding toner image; a toner feeding member rotatable in contact with said developer carrier to thereby feed the toner to said developer carrier; toner conveying means for conveying the toner toward said toner feeding member; a metering member contacting said developer carrier and configured to regulate an amount of the toner deposited on a surface of said developer carrier by said toner feeding member; and a regulating member configured to regulate an amount of the toner deposited on a surface of said toner feeding member; wherein, during development, said developer carrier is rotated such that the surface thereof moves vertically upward at a position where said surface faces an image carrier, while said toner feeding member is rotated such that a surface thereof moves in a same direction as said surface of said developer carrier at a position where said toner feeding member faces said developer carrier.
