Abstract: PURPOSE:To prevent an accumulation of a mixed toner by a simple constitution, and to stabilize a distinct picture image for a long period of time by adsorbing the mixed toner of a different polarity mixed into a developing device, by a non- image area onan image carrier electrostatically charged to the polarity opposite to said polarity, and discharging it to the outside of a device. CONSTITUTION:A non-image area provided by some width on both sides of an image area of a photosensitive body 1 is electrostatically charged to the negative polarity together with the image area at the time of the first electrostatic charge. Subsequently, each stage of the first exposure, the second electrostatic charge, the second exposure and the first development is executed to an image area B, and the non-image area is not influenced by them. Next, when the second development is executed to the whole area A, a red toner RT of the negative polarity does not adhere to the non-image area at all, but it is scraped down at the time of the second development, and only a black toner BT of the positive polarity by the first development mixed in the second developing device adheres to the non-image area. This black toner reaches a cleaner as it is, and it is discharged to the outside of a device. In this way, the mixed toner is removed, and the image is held distinctly and stably for a long period of time.
