    摘要： In an electrophotographic apparatus, regions having at least three different potential levels Vc, Vw, and Vr are formed on a photosensitive member by using an exposing device, and developing processes respectively using colored particles of different kinds are performed by normal development and reversal development on two potential levels Vc and Vr excluding the intermediate potential level Vw. The apparatus has an auxiliary exposing unit for forming a fringe development preventing potential in an edge of an image forming region in order to prevent fringe development from occurring. The auxiliary exposing unit sets an auxiliary exposure amount by performing pulse-width modulation on a laser driver.

    摘要： A color electrophotographic printer having a printing process which records a toner image of one color or two colors in a pixel by one exposure. The color electrophotographic printer includes a memory which stores exposure data corresponding to respective pixels of input data of an image, a photosensitive body and at least one charger which charges the photosensitive body. At least one exposing machine exposes respective pixels on the photosensitive body based on the exposure data and a developing machine develops toner of one color or two colors in the exposed respective pixels and forms a toner image. A transfer machine transfers the toner image onto a printing medium and a fixing machine having a belt which fixes the transferred toner image on the printing medium. The belt is controlled so that a relative speed difference occurs between the printing medium and the belt at a position along the belt at least when the developed toner of two colors in one pixel of an image of the printing medium is fixed.
