Abstract: A conveyance device includes a housing, a formation member, and a detection section. The housing has a first conveyance path, a second conveyance path, and a first communication path. The first and second conveyance paths each are a conveyance path for conveying a developer. The first communication path allows a first end portion of the first conveyance path and a first end portion of the second conveyance path to be in communication with each other via a communication surface. The communication surface has a first region and a second region. The formation member forms the second region of the communication surface so that a height of the second region from a bottom portion of the first communication path is lower than a height of the first region from the bottom portion of the first communication path. The detection section detects the amount of the developer.

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.
