Abstract
A developing device includes a housing, a developer carrier, a conveying member and a surface layer. The conveying member conveys the developer in the first conveying direction and supplies the developer to the developer carrier. The surface layer is arranged on the circumferential surface of the developer carrier and formed on a surface of a predetermined cylindrical base member. The surface layer is formed by an immersion method of immersing the base member in an immersion tank so that an axial direction of the base member extends along a vertical direction. A lower end side of the base member at the time of the immersion is arranged in a downstream side of the housing in the first conveying direction and an upper end side of the base member at the time of the immersion is arranged in an upstream side of the housing in the first conveying direction.
