Developing unit and wet image forming apparatus having the same

摘要

The developing unit has a developer receptacle containing liquid developer, a deposit roller rotatively disposed substantially below a surface of the liquid developer of the developer receptacle, a developing roller rotatively disposed over the deposit roller so that a part thereof submerges in the liquid developer and a metering roller rotatively disposed on a side of the developing roller over the surface of the liquid developer. The level of the liquid developer is maintained so that an angle between a first straight line joining a rotational center of the developing roller and a first intersection point where a circumferential surface of the developing roller intersects with the surface of the liquid developer below the metering roller and a second straight line joining the rotational center and a rotational center of the deposit roller is over about 20°.
