PURPOSE:To increase transfer efficiency and to obtain an image without paint out by changing a squeezing squantity with an excess liquid removing means based on image data. CONSTITUTION:An exposure data summing up device 33 attains conversion into a voltage value to be applied to a corona discharger 53, based on the image data A of ana original read by a reader 31 and applies the voltage value to the corona discharger 53 or a squeezing roller 57. Moreover, a control electrode having thin wire electrodes almost corresponding each of a prescribed number of picture elements in the axial direction of a photosensitive drum 1 is provided on a corona discharger or an electrode almost corresponding to each of a prescribed number of the picture elements is provided on a squeezing roller. Then, the voltage value converted in each of a prescribed number of the picture elements based on the picture data is applied to the thin wire electrode or the electrode. |
