Abstract

An image forming apparatus allowing an image carrier included therein to be desirably cleaned is disclosed. A developing device uses a developing liquid consisting of a carrier liquid and toner dispersed therein. A toner image produced by the developing device is transferred to an intermediate image transfer belt. A cleaning roller cleans the surface of the intermediate image transfer belt after the transfer of the toner image to a paper sheet or similar recording medium. A liquid cleaning device feeds a cleaning liquid to the cleaning roller. The developing liquid may be replaced with a dry developer containing at least powdery toner.
