Abstract
A liquid developing apparatus includes a developing roller for developing a latent image on a surface of a photoconductor belt by using a liquid developer. The developing roller is opposed to the surface of the photoconductor belt. A cleaning electrode is provided to remove toner particulates from the surface of the developing roller. The cleaning electrode is opposed to the developing roller with a predetermined distance. A first voltage and a second voltage are applied to the developing roller and the cleaning electrode, respectively. The second voltage applied to the cleaning electrode has an AC component to remove toner particulates from the developing roller.
