摘要： An image fixing unit for a wet image forming apparatus comprises a fixing section and a preheating means. The fixing section has a first fixing roller, and a second fixing roller which rotates in close contact with the first fixing roller to feed paper through a gap (a fixing nip) between the first and second fixing rollers. The preheating means is disposed on a feed path of the paper before the paper enters the fixing nip, and comes into contact with a non-image surface of the paper to allow the image to be exposed to the air. Either one of the first and second fixing rollers is disposed to bring a surface thereof into contact with the non-image surface of the paper before the paper passes through the fixing nip, and the fixing roller brought into contact with the paper has a heating element mounted therein.

摘要： A image forming apparatus having a developer controlling apparatus for a developing roller is provided to uniformly control an amount of developer deposited on the developing roller and a developer controlling method thereof. The apparatus includes a sensing part having a first sensor which senses a conductivity of a liquid developer and a second sensor which senses a density of the liquid developer. A control part controls a voltage applied to the developing roller and/or a deposit roller according to the conductivity and the density sensed by the sensing part.

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°.

摘要： An image fixing unit for a wet image forming apparatus comprises a fixing section and a preheating means. The fixing section has a first fixing roller, and a second fixing roller which rotates in close contact with the first fixing roller to feed paper through a gap (a fixing nip) between the first and second fixing rollers that are in close contact. The preheating means is disposed on a feed path of the paper before the paper enters the fixing nip, and comes into contact with a non-image surface of the paper (a surface of the paper on which no image is formed) to allow the image to be exposed to the air. An exemplary embodiment of the preheating means is a belt that is disposed on the feed path of the paper and is supported by a preheating roller spaced a predetermined distance apart from the first fixing roller to move along an endless path, so that the belt is adapted to be fed in contact with a non-image surface of the paper. Either one of the first and second fixing rollers is disposed to bring a surface thereof into contact with the non-image surface of the paper before the paper passes through the fixing nip, and the fixing roller brought into contact with the paper has a heating element mounted therein.
