Developing cartridge and image forming apparatus using the same
A developing device for an image forming apparatus of the present invention includes a developer carrier for depositing toner on a latent image formed on an image carrier to thereby produce a toner image. A toner feeding member is rotatable in contact with the developer carrier to thereby feed the toner to the developer carrier. A metering member contacts the developer carrier for metering the toner deposited on the developer carrier while a regulating member regulates the toner deposited on the toner feeding member. During development, the developer carrier is rotated such that its surface moves vertically upward at a position where the surface faces an image carrier, while the toner feeding member is rotated such that its surface moves in the same direction as the surface of the developer carrier at a position where the toner feeding member faces the developer carrier.
