PURPOSE:To provide high definition image characteristic superior in highlight reproduction and thin line reproduction, etc., and to perform image formation superior in durability and stability. CONSTITUTION:In an electronic photographic copying machine in which a cleaner equipped with an elastic cleaning blade 2 to eliminate a residual developer by pressurizing on a photosensitive material 1 is located at the upper part of the photosensitive material 1, the pressurizing force of the cleaning blade 2 for the photosensitive material 1 is set at 25-45g/cm, and the photosensitive material is formed with an organic photosensitive material on the surface of which fluorocarbon resin powder of 5-40wt.% is contained, and a developer to be used consists of at least a nonmagnetic coloring agent containing resin particle and an outer fitting agent, and the outer fitting agent contains at least a floating improving agent and a spherical particulate of weight mean grain diameter 0.2-2.5mum. |
