To provide a cleaning apparatus capable of maintaining high cleaning performance even if surface roughness of an image carrier is increased due to wear and a wet image forming apparatus installing the concerned cleaning apparatus, thereby enabling to form images of a stable quality. The cleaning apparatus for removing liquid developer remaining on the surface of a latent image carrier and an intermediate transfer member, which are an image carrier of the image forming apparatus for forming images with the liquid developer including toner particles and carrier liquid, includes three stages of cleaning sections such as a preliminary cleaning member for making contact with the image carrier and suspending the toner particles adhered to the surface of the image carrier in the carrier liquid, a toner particles removing member for removing the suspended toner particles by electrostatic force, and a carrier liquid removing member for removing the remaining carrier liquid.
