ABSTRACT:
There is provided a simply structured, cleanerless image forming apparatus capable of suppressing occurrence of filming without significant remodeling.An image forming apparatus100according to the present invention comprises a plurality of image forming units100a, 100b, 100c, and100dfor forming toner images of corresponding colors on photoconductor drums3a, 3b, 3c, and3daccording to a cleanerless system. These image forming units respectively have adhered toner film cleaners1a, 1b, 1c, and1deach of which touches a surface of the photoconductor and mechanically cleans the surface at every cleaning timing for cleaning the surface of the photoconductor. The adhered toner film cleaner does nothing during image formation, but cleans the photoconductor surface only at cleaning timing when the image formation is complete for the specified number of sheets. Accordingly, it is possible to decrease filming without affecting the photoconductor's life.
