ABSTRACT:
A developing apparatus having a developing container for containing developer including toner and carrier, and developing an electrostatic image formed on an image bearing member, includes a carrying member for carrying the developer in the developing container, and a discharge port provided in the developing container for discharging any excess developer resulting from the supply of the developer. The developer carrying capability of the carrying member is greater in an area near the discharge port than in an area downstream of the discharge port in the carrying direction of the developer.
