<p>PURPOSE:To make the reproducibility of an image satisfactory in development with use of magnetic one-component toner by making the strength of the magnetization of the magnetic one-component toner small and stabilizing a process for imparting a charge to toner. CONSTITUTION:In the image forming device provided with a latent image carrier 10, a latent image forming means forming a latent image on the latent image carrier 10, magnetic toner incorporating a magnetic substance, a developer carrier 1a and a developing device carrying the developer incorporating the magnetic toner and developing the latent image on the latent image carrier 10, the magnetic toner incorporates the magnetic substance composed of a metallic oxide whose magnetization strength in 1KOe (oersted) magnetic field is 10-40emu/g and ferri-diameter in a horizontal direction is 0.05-0.5mum and at least two or more developing carriers 1a are disposed.</p> |
