摘要:
An image forming apparatus includes a developing device for developing an electrostatic image formed on an image bearing member with a magnetic developer; a supply tube for supplying the magnetic developer into the developing device; a feeding screw for feeding the magnetic developer in the supply tube; a magnetic member for confining the magnetic developer in a clearance between the supply tube and the feeding screw, wherein the magnetic member is extended along an outer configuration of the feeding screw.
