Claims

A developing roller carrying a liquid developer having toner and carrier liquid;
An anilox roller having a groove and supplying the liquid developer to the developing roller;
A supply roller for contacting the anilox roller and supplying the liquid developer to the anilox roller;
Voltage application means for applying an AC bias to the supply roller;
A developer storage section for storing the liquid developer supplied to the supply roller;
A developing device comprising:

The developing device according to claim 1, wherein a DC voltage is applied to the developing roller, and a DC voltage that is the same as the DC voltage applied to the developing roller is applied to the supply roller.

The developing device according to claim 1, wherein the AC bias applied to the supply roller is a rectangular wave.

The developing device according to claim 1, wherein the anilox roller and the supply roller are rotated in the same direction.

A developing roller carrying a liquid developer having toner and carrier liquid;
An anilox roller having a groove and supplying the liquid developer to the developing roller;
A regulating blade that regulates the amount of the liquid developer that the anilox roller supplies to the developing roller in contact with the anilox roller;
Voltage application means for applying an AC bias to the regulating blade;
A supply roller for supplying the liquid developer to the anilox roller;
A developer storage section for storing the liquid developer supplied to the supply roller;
A developing device comprising:

The developing device according to claim 5, wherein a DC voltage is applied to the developing roller, and a DC voltage that is the same as the DC voltage applied to the developing roller is applied to the regulating blade.

The developing device according to claim 5, wherein the AC bias applied to the regulating blade is a rectangular wave.
