Image recording method

Abstract

Abstract PURPOSE:To form a two-color toner image of stable quality by a simple device by combining three kinds of technique, i.e. the switching of an exposing means, two-color ambipolar development, and simultaneous transfer and fixation utilizing an intermediate transfer body. CONSTITUTION:A photosensitive body 1 which is constituted by providing a photoconductive layer on a substrate 12 is charged electrostatically and uniformly by an electrostatic charger and then exposed to a background part so that the potential of the background part remains. Then, the photosensitive body 1 is exposed to an image part to form an electrostatic latent image of ternary level. The formed electrostatic latent image is visualized with two kinds of insulating toner 51 and 52 which are charged electrostatically to the opposite polarities and differ in color. Their toner images are transferred to the intermediate transfer body 6 by bringing said body 1 and said body into contact with each other. The transferred toner images are transferred to recording paper 8 by pressing the intermediate transfer body 6 and a press-contacting roll 7 across the recording paper 8 and fixed.
