ABSTRACT:
An image forming apparatus including an image carrier, an image data storing device for storing image data, a latent image forming device for forming a first latent image on the image carrier in a state of negative image of said image data and for forming a second latent image on a copy sheet or the like in a state of a positive and mirror image of the image data. The image forming apparatus further includes a developing device for negatively developing the first latent image with toner, a feeding device for synchronously feeding the sheet with rotation of the image carrier toward a toner transfer station of the image carrier and a toner image transfer device for transferring the toner image onto the second latent image carried on the sheet or the like at the toner transfer station to superimpose the toner image on the second latent image.
