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.
