Abstract

A printer or copier and method generates toner images for transfer onto a recording medium. A latent charge image is generated on a photoconductor and is developed by the application of toner by at least one developer station to generate the toner image for transfer to the recording medium. A plurality of the developer stations are provided along the photoconductor to develop the images in color using a color separation method. A transfer band collects the color separations on top of one another to generate the overall toner image which is transferred to the recording medium. Multiple modules, each with developer stations, a photoconductor and a transfer band may be provided for one sided or two sided printing.
