Abstract: A development device includes a developer introduction port, a developer conveyance portion, a first conveyance ability suppressing portion, and a connecting conveyance portion. The conveyance ability suppressing portion is disposed on a downstream side of the developer introduction port in a first direction in which the developer is conveyed in order to partially suppress a developer conveyance ability of the developer conveyance portion such that a developer accumulation portion is formed in a position opposing the developer introduction port. A first direction downstream side of the first conveyance ability suppressing portion opposes a first connecting passage in a third direction that intersects the first direction. The connecting conveyance portion is joined to the first direction downstream side of the conveyance ability suppressing portion and opposes the first connecting passage in the third direction in order to pass the developer from a first conveyance passage to a second conveyance passage.
