Abstract

PURPOSE: To obtain a desired quality image when an electrostatic image formed on the image support body, such as, photo-sensitive body, is developed by using a mass of toner which has a special resistivity value at a specific region, and changing the charging potential of the toner in accordance with the kind and purpose of the image.
