PURPOSE:To prevent the disturbance of a toner image at the time of reelectrification or development by increasing the adhesiveness of the toner to a photosensitive body to a multicolor image forming device forming a multicolor image with one rotation of the photosensitive body. CONSTITUTION:Plural image recording parts 5-8 which are provided with electrifying devices 21, 25, 29, 33, exposing devices 22, 26 30, 34 and developing devices 24, 28, 32, 36 respectively and forms toner images having different colors with one another on the photosensitive body 3 are arranged successively along the surface of the photosensitive body 3, and simultaneously, electric field imparting devices 27, 31, 35 apply electric fields to the toner image formed by preceding image recording parts are disposed on the upper stream side of developing devices 28, 32, 36 in the second and subsequent image recording parts 6-8. A toner image is pressed to the photosensitive body side by the electric field from the electric field imparting device and the adhesiveness of the toner to the photosensitive body is increased.
