Abstract
PURPOSE:To always form an electrostatic image havng uniform potential, on a photosensitive body, by varying the quantity of charge of primary charge, and the bias electric field for transfer, in the increase or decrease direction by the same time constant, as the number of times for forming a latent image increases. CONSTITUTION:An image is formed continuously by executing a process including charge and exposure, to a photosensitive body 1 having a photoconductive layer and a conductive supporting body, and the quantity of charge is corrected by utilizing not only a variation of the charge potential of the photosensitive body 1 by a primary discharger 5, but also a variation of the charge of the photosensitive body 1 by a transfer discharger 10. Also, as the number of times of repetition for forming a latent image to the photosensitive body 1 increases, a current applied to the primary corona discharger 5, and a current applied to the transfer discharger 10 are lowered like an expotential function, and they are corrected so as to keep constant at the tenth time and therefore. In this way, an electrostatic image having uniform potential is always formed on the photosensitive body 1.
