Abstract:
A liquid developing apparatus using a liquid developer including toner particulates, comprising:a developing roller for developing an electrostatic latent image on a surface of a photoconductor member by using a liquid developer, wherein the developing roller is opposed to the surface of the photoconductor member with a first predetermined distance;a liquid developer reservoir for storing the liquid developer;a liquid developer supplying member for supplying the liquid developer to the developing roller;a cleaning electrode for removing toner particulates from a surface of the developing roller, wherein the cleaning electrode is opposed to the developing roller with a second predetermined distance and the cleaning electrode is positioned below the developing roller within the liquid developer reservoir; anda power supply for applying a first voltage and a second voltage to the developing roller and the cleaning electrode, respectively, the second voltage applied to the cleaning electrode having an AC (alternating current) component with a predetermined peak-to-peak amplitude and a predetermined frequency.
