Abstract: PURPOSE:To obtain high transfer image density by carrying out transfer processing wherein the electrostatic charging polarities of toner images which differ in polarity are uniformed and the difference in the quantity of charges between both the toner images is adjusted to a specific value. CONSTITUTION:This method is equipped with a uniform exposure lamp 7 which exposes a photosensitive drum 1 uniformly after a developing process and before a transfer process, a before-transfer electrostatic charging corotron 8 which utilizes AC corona discharging for equalizing the electrostatic charging polarities of toner images on the photosensitive drum 1, and a transfer corotron 9 which charges a recording sheet 10 to the opposite polarity from the polarity of the toner image uniformed by the before-transfer electrostatic charging corotron 8 and transfers the respective color toner images electrostatically to the recording sheet 10. Then the difference in the quantity of charges between both the toner image is adjusted to <=10muc/g in the process of uniforming the polarities of the toner images which differ in polarity to prevent the quantity of charges of the toner images which are charged electrostatically to the polarities to be uniformed from increasing extremely, and the transfer rates of both the toner images to the recording sheet 10 almost become equal in a high state. Consequently, the high transfer image density is obtained.
