<p>PURPOSE:To obtain a one-color image which can be projected as a two-color image by making coarse the surface of an image formed on one side of a transfer sheet. CONSTITUTION:A photosensitive body 5 is subjected to image formation wherein a projected color varies with an image and development in order. A firstly formed toner image is transferred onto an intermediate transfer body. A secondarily formed toner image is directly transferred onto the surface of the transfer sheet, and simultaneously the first toner image on the intermediate transfer body is transferred onto the rear surface of the transfer sheet TS. Either the first or second toner image that is formed on the front or back of the transfer sheet TS is made coarse by a coarsening means. Consequently, they appear as a two-color image corresponding to black color and toner color on a screen.</p> |
