摘要：
An object of the present invention is to provide a developing apparatus capable of reducing unevenness of density of an image in a longitudinal direction of a photosensitive member. For this purpose, in the present invention, a developing apparatus includes a developer bearing member, and a developer carrying screw placed adjacently to the developer bearing member in parallel with the developer bearing member, and an inclination angle of “a carrying surface facing in a developer carrying direction of a spiral blade of the developer carrying screw” to a shaft of the developer carrying screw is equal to or less than 60 degrees.
