Method of forming a multicolor toner image on a photoreceptor and transferring the formed image to a recording sheet

摘要

An image forming machine such as a copier or a printer for forming a multi-color toner image on a photoreceptor. The machine includes: a charger for charging the photoreceptor; an exposer for forming a latent image onto the photoreceptor; plural developers for developing the latent image on the photoreceptor with one of plural different color toners so that the toner image of one of the plural color toners is obtained; in which plural toner images, each of which is formed by one of the plural developers, are superimposed so that a multi-color toner image is formed on the photoreceptor; a re-exposer to re-exposing the multi-color toner image on the photoreceptor; a transferrer for transferring the multi-color toner image onto a recording sheet; in which the transferrer presses the recording sheet onto the photoreceptor for transferring the multi-color toner image from the photoreceptor to the recording sheet; and a cleaner for removing a residual toner on the photoreceptor after the transfer of the multi-color toner image onto the recording sheet; in which the cleaner is brought into contact with the photoreceptor for cleaning the residual toner. In the image forming machine, at least one of the transferrer and the cleaner starts functioning after re-exposing by the re-exposer is completed.
