Abstract
In an image forming apparatus, a developing device develops an electrostatic latent image formed on an image carrier with a developing liquid to thereby produce a corresponding toner image. The toner image is transferred from the image carrier to an intermediate transfer body. To increase a transfer ratio from the intermediate transfer body to a paper or similar recording medium, charge applying device applies to the toner image transferred to the intermediate transfer member a charge identical in polarity with toner particles forming the toner image. A roller member faces the surface of the intermediate transfer body to which the toner image is transferred for cleaning the transfer body and removing a carrier liquid. The roller member also controls the amount of carrier liquid on the intermediate transfer body.
