A cleaning device of this invention has a first cleaning member that is provided opposing to a developer image carrier for the scraping of the surface of the developer image carrier and a second cleaning member that is put over the first cleaning member and runs between the surface of the developer image carrier and the first cleaning member for the wiping of the surface of the developer image carrier simultaneously with the scraping of the surface of the developer image carrier by the first cleaning member. This cleaning device is used for cleaning of the developer image carrier of an image forming apparatus.

Cleaning device and image forming apparatus including first and second cleaning members

An image forming apparatus includes a latent image forming mechanism for forming an electrostatic latent image on a photosensitive member, and a developing device for supplying a developing liquid containing at least toner and a carrier liquid, to the photosensitive member on which the latent image is formed, thereby to develop the latent image. The image forming apparatus also includes a removing device for removing an excessive portion of the developing liquid supplied by the developing device, whereby the excessive portion of the developing liquid remains on the photosensitive member after development. The image forming apparatus further includes a returning mechanism for returning the excessive portion of the developing liquid, which is removed by the removing device, into a casing of a developing liquid supply unit for supplying the developing liquid to the developing device, and a reserve flow-in section. The reserve flow-in section has a float and is provided in front of a developing liquid container section in the casing of the developing liquid supply unit, thereby to return the developing liquid to the reserve flow-in section when the valve is opened.
