Abstract
An image forming machine such as a copier and a printer for forming a color image on a recording sheet. The image forming machine includes: a photoreceptor for carrying the color image; an image writer such as a laser beam generator for forming a latent image of the color image on a surface of the photoreceptor; plural color developers for developing the latent image with color toners so that a developed color image is formed on the surface of the photoreceptor; a transferer for transferring the developed color image from the photoreceptor to the recording sheet; a cleaner for cleaning a residual portion of the developed color image on the photoreceptor; and a controller for controlling a cleaning operation of the cleaner which starts the cleaning operation after the transferring operation is completed. In the image forming machine, the plural color developers, the transferer, and the cleaner are located facing toward the surface of the photoreceptor, and a length of the surface between the transferer and the cleaner through the plural color developers is longer than a length of the color image. In addition, the image writer, the plurality of color developers, the transferer and the cleaning device are located in a specific order around the photoreceptor.
