ABSTRACT:
An image forming apparatus includes a data processing device to process image information. A latent image forming device forms an electrostatic first latent image on a surface of a photoconductive element based on image data processed by the data processing device and forms an electrostatic second latent image on the photoconductive element. A developing device develops the first and second electrostatic latent with toner. The first latent image is transferred from the surface of the photoconductive element to a transfer sheet, and the transfer sheet is separated from the surface of the photoconductive element by a separation pick. And, the second latent image has a pattern not produced in a portion of the surface of the photoconductive element that corresponds to the separation pick.
