Abstract
The developing apparatus includes developer containing parts and a replenishment portion. The developer containing parts contains a developer circularly conveyed in the developer containing parts. The replenishment portion includes a replenish aperture and a regulation surface. The replenishment portion merges a replenishment agent passing through the regulation surface with the developer in the developer containing part. In the developing apparatus, a wall surface of the replenishment portion, located on a downstream side in a developer conveyance direction in the developer containing part facing to the replenishment portion, is formed by being inclined with respect to the developer conveyance direction.
