PURPOSE:To provide an inexpensive image forming device in which a recording sheet is steadily attracted. CONSTITUTION:In the image forming device which is provided with a PCL, a scorotron electrifier, a laser writing device, a plurality of developing units, a transfer belt device 30, a cleaner, etc., around the periphery of a photosensitive drum 10 as an image carrier and which forms a multicolor toner image by repeating an electrification/image exposure/development process to superimpose toner images on the photosensitive drum 10, the transfer belt device 30 divides the output of a high voltage power source 41, which supplies a bias voltage to the transfer unit 36 of the transfer belt device 30, by means of a resistor R1 and a Zener diode ZD as a non-linear element, thereby supplying the bias voltage to be applied to a holding roller 32 used for attracting a sheet of recording paper P to a transfer belt 31. |
