Abstract:
A development device includes a developer container reserving a liquid developer containing toner particles and a carrier liquid. A developer supply member supplies a developer supporting member with liquid developer. An agitating member is disposed in the developer container and supplies the developer supply member with the liquid developer. A developer supporting member cleaning member removes liquid developer on the developer supporting member. The developer container includes a first developer holding section having at least one communication section for making liquid developer flow in, a second developer holding section for reserving liquid developer recovered by the developer supporting member cleaning member, and a partition member partitioning between the first and second developer holding sections, and at least one flowing section shifted from the communication section in an axial direction of the agitating member and allowing liquid developer to move between the first and second developer holding sections.
