In a developing device which supplies a liquid developer to a developer holder roller using a supply member and performs development using the liquid developer, and an image forming apparatus including the developing device, a developer holder cleaning unit which cleans the developer holder roller and recovers the liquid developer in order to prevent the liquid developer after development from being adhered to the supply member, a supply member cleaning unit which cleans the supply member and recovers the liquid developer, a recovery path member which is disposed above the supply member in a vertical direction and receives the liquid developer recovered by the developer holder cleaning unit, and a recovery unit which is disposed above the recovery path member in the vertical direction and stores the liquid developer moved to the recovery path member and the liquid developer recovered by the supply member cleaning unit are provided.
摘要:
A driving force produced by a first driving motor is transmitted to a developing roller and an intermediate application roller by a first drive transmission unit, and the developing roller and the intermediate application roller are rotated as a result. The developing roller and the intermediate application roller thus take the first driving motor as a drive source, and receive the driving force from the first driving motor via the same first drive transmission unit. As a result, the phases of the fluctuation in a rotational component of the first driving motor and the cyclic fluctuation of gear interlocking match, which reduces a rotational velocity difference between the developing roller and the intermediate application roller.

Provided is an image forming apparatus including: a latent image carrying drum on which a latent image is formed; a charging section that includes a corona charger charging the latent image carrying drum and an air flow duct formed in the corona charger so as to be long in the rotation axis direction of the latent image carrying drum so that air flows in the corona charger; a developing section that is disposed above the air flow duct in the vertical direction, is formed so as to be shorter than the air flow duct in the rotation axis direction of the latent image carrying drum, and develops the latent image formed on the latent image carrying drum by a liquid developing agent including toner and a carrier liquid.

An image forming apparatus of the invention includes a carrier solution application roller that rotates centering on a rotary shaft and applies a carrier solution to a transfer roller after an image of a liquid developer including toner and the carrier solution is transferred to a transfer medium, a transfer roller cleaning roller, supported by a cleaning member support portion through a rotary shaft, which removes toner remaining in the transfer roller, and a carrier solution application roller of which the amount of movement is larger than the amount of movement of the transfer roller cleaning roller when the cleaning member support portion is rotated. Even when the transfer roller moves, satisfactory cleaning properties are secured without breaking a mutual positional relationship by facilitating mutual positioning between the transfer roller and the transfer roller cleaning roller.
摘要:
Developer is recovered by a development unit, a first squeeze unit, a second squeeze unit, and a photoreceptor cleaning unit, but the developer recovered by the development unit or the first squeeze unit has a relatively high concentration, and is therefore returned to a stirring tank for reuse. The developer recovered by the second squeeze unit or the photoreceptor cleaning unit has a relatively low concentration, and is therefore accumulated in a buffer tank separate from the stirring tank to prevent the toner concentration in the stirring tank from decreasing.

A developing device includes: a developer storage portion which stores a liquid developer including toner and carrier liquid; a first coating member which rotates and coats the liquid developer stored in the developer storage portion; a second coating member which comes into contact with the first coating member and rotates in a direction opposite to that of the first coating member and slower than a rotary peripheral velocity of the first coating member; and a developer supporting body which comes into contact with the second coating member and rotates in the same direction as that of the second coating member and faster than a rotary peripheral velocity of the second coating member.
摘要:
A developing device includes a developer storage portion that stores a liquid developer including toner and carrier liquid. A first coating member rotates and coats the liquid developer stored in the developer storage portion. A second coating member contacts the first coating member and rotates in a direction opposite to that of the first coating member. A developer supporting body contacts the second coating member and rotates in the same direction as that of the second coating member. A contact member contacts the liquid developer coated on the second coating member by the first coating member.
