Abstract

PURPOSE:To stabilize reproduced images by measuring the potential of a photoreceptor surface and correcting developing characteristics according to the measured value. CONSTITUTION:A bias source 19 is connected to a developing roller 15 and the measured voltage is further increased to a higher voltage to prevent the occurrence of photographic fogs owing to the change in the surface potential of the photosensitive drum. When the toner polarity is negative, an electric power source 20 which is positive on the developing roller 15 side and negative on the applicator roller 18 side is connected between both rollers 15, 18 and is so connected to a control system that the source voltage thereof fluctuates according to the potential value of latent image contrast. Thereby, the reproduction of stable images is made possible.
