The invention is directed to a paper dust removing device used in an image forming apparatus. The image forming apparatus has a latent image member that receives the latent image produced by a charge differential on the surface of the latent image device. A developing agent, or toner, is then applied to the latent image creating a visible image. The toner image is transferred to a paper as it passes between the latent image member and a transferring roller or device and subsequently processed to adhere the toner image to the paper. The apparatus further has a paper dust removing device that removes paper dust from the latent image member. A biasing device applies an electrical bias to the paper dust removing device to produce a potential difference between the latent image member and the paper dust removing device. As the total amount of formed images increases, it is necessary to control the biasing device to vary the bias applied to the paper dust removing device to preclude adhering toner, that remains on the latent image device, to the paper dust removing device.
