とを特徴とする画像形成装置。 an image carrier whose circumferential surface is divided into a photoconductive region and a non-photoconductive region; a charger for uniformly charging the circumferential surface of the image carrier; and a photoconductive device for the uniformly charged image carrier. An electrostatic latent image forming means for forming an electrostatic latent image by imagewise exposure to a magnetic area, and a developer containing a high resistance magnetic toner and magnetic particles having a lower resistance than the high resistance magnetic toner. It has a developing device to which a bias voltage is applied to rub the peripheral surface and develop the electrostatic latent image with toner, and a transfer device that transfers the developed toner image onto a transfer material. An image forming apparatus characterized in that the magnetic particles are absorbed and consumed in the non-photoconductive area.
