Abstract

PURPOSE:To supply a developer to the latent image surface of a photoreceptor securely by providing a conductive rotatable body in a container, and then charging and supplying the developer to a supplying means by applying a voltage to the rotatable body. CONSTITUTION:At the lower part in a toner container 3, a conductive roller 4 is provided rotatably, and under it, a developer supplying means made of a magnet roll 5 and a sleeve 6 is provided in contact with or at about 1mm. interval to the roller 4. The conductive roller 4 and magnet roll 5 are connected to a bias power source 8; when the conductive roller 4 is rotated, magnetic toner (a) sticking to the roller 4 is regulated by a regulating piece 7 and carried, and the charging polarity of the toner (a) at this time is determined by the polarity of the bias power source 8 and selected according to the polarity of the latent image formed on a photoreceptor 1.
