PROBLEM TO BE SOLVED: To provide an image forming device constituted so that toner is efficiently recycled and a stable image can be formed. SOLUTION: The image forming device 2 is provided with a developing device 14 supplying toner to a latent image formed on a photoreceptor drum 10 and developing it, a toner recycling mechanism 20 returning the toner recovered from the drum 10 by a cleaning device 18 after a toner image formed on the drum 10 by the developing device is transferred on a paper by a transfer device 16 to the developing device and an attraction roller attracting impurity in a developwer returned by the recycling mechanism 20 by an attraction bias voltage related to potential difference and polarity regulated based on the charged polarity of the toner and a developing bias voltage impressed on the developing roller 14a of the developing device and the toner. |
