Patent number: 4486088Abstract: A novel method and apparatus for electrophotography is disclosed which enables selection the mode of image formation among positive-positive, negative-positive and combinations thereof without any need of changing the polarity of developing toner. The present invention is made on the basis of a known electrophotographic system in which a photosensitive member composed of essentially an electrically conductive substrate, a photoconductive substance layer and an insulating surface layer and which comprises the steps of charging the insulating surface layer, image-wise exposing it to light so as to form a first image almost simultaneously with or some time after the charging step, subjecting it to corona discharge with nearly simultaneous image-wise exposure so as to form a second image and uniformly exposing the whole surface of the photosensitive medium to light so as to form an electrostatic latent image corresponding to a composite image resulting from the first and second images.Type: GrantFiled: May 28, 1982Date of Patent: December 4, 1984Assignee: Canon Kabushiki KaishaInventors: Takashi Kitamura, Michio Ito

Patent number: 4329413Abstract: The present invention is directed to process and apparatus for overlaying images making use of steps constituting a known electrophotographic process. The electrophotographic process on which the present overlay process depends is of the type in which a three-layered photosensitive member having an insulating covering layer as the top layer of the member is used. The surface of the insulating layer is charged with an electric charge simultaneously with an imagewise irradiation for a first image to be overlaid or during the time of a photo hysteresis resulted from the first image-forming irradiation being still present in the photoconductive layer of the photosensitive member. Then, AC discharging or charging with an electric charge of opposite polarity to that of the above electric charge is effected. Thereafter, an imagewise irradiation for second image is carried out to obtain an electrophotographically overlaid image from the first and second images.Type: GrantFiled: February 15, 1980Date of Patent: May 11, 1982Assignee: Canon Kabushiki KaishaInventors: Takashi Kitamura, Michio Ito
