ABSTRACT:
In the tri-level process in which positive and negative latent images are formed on a photosensitive body and then developed using toners of two colors (for example, red and black) charged respectively to opposite polarities with respect to the polarities of the latent images, there has been a problem of degrading the quality of a two-color picture by the appearance of a special phenomenon in which red toner is attached around a black image and black toner is attached around a red image by attraction of the reverse electric field. An exposure control is performed in order to suppress the fringe phenomenon.
