PURPOSE:To increase a printing speed and prevent the positional shift between respective color toner images by forming a plurality of indicated color electrostatic latent images on a photosensitive member by one exposure to simultaneously develop them by a plurality of processors and transferring a plurality of developed color toner images. CONSTITUTION:A charger 271, an exposure optical system 272, first and second processors 273, 274, a charger 275, a destaticizer 276 and a cleaner 277 are arranged around a photosensitive drum 255 in the rotary direction of the drum 255. A photosensitive drum 256 is constituted in the same way. Photosensitive drums 255, 265 are charged by chargers 271, 281 and exposure optical systems 272, 282 control exposure intensities and exposure widths corresponding to colors to be bonded to perform exposure. Subsequently, respective color toner images are developed by processors 273, 283, 274, 284 and re-charged by chargers 275, 285 so as to have polarity bonding toners to recording paper 300. The charged toner images are transferred to the recording paper 300 at transfer points 254, 264. |
