Abstract: A developing apparatus capable of suppressing an excessive discharge of developer from a developer discharge hole is disclosed. A first opening part through which developer is carried from a first case part to a second case part, and a developer discharge hole through which the developer is discharged are provided to the first case part. A first carrying member includes a counter blade between the first opening part and the developer discharge hole. The counter blade carries the developer in an opposite direction to a carrying direction of a first carrying blade of the first carrying member. A gap is prepared between an upper part of the counter blade and the first case part. A cross-sectional area of a discharge path for the developer from the counter blade to the developer discharge hole changes according to a progress of the developer along the discharge path.
