PURPOSE:To constitute a titled device so that a distance between a toner thin layer and an electrode is kept constant, and also charge to the thin layer becomes uniform and is not put into disorder, by forming as one body a toner measuring member using a blade, and a recording electrode. CONSTITUTION:One end 12 of an upstream side of a toner vessel 3 is formed by a ferromagnetic material, a magnetic pole N of a magnet 2 is provided in the vicinity of a toner carrying member 1 and opposingly, a brush is formed on one end 12, and a residual image is erased by slide-rubbing the toner carrying member by this brush. The brush of this one end part 12 prevents a drop of a toner from the vessel. Also, as the case may be, a residual image is generated by forming a magnetic field, too, but in this case, a magnetic material blade 13 contacting with other carrying member 1 is provided, and at an opposed position, a magnetic pole S is provided. In this case, by providing the magnetic material blade in multistage, a toner thin film is formed on the toner carrying member more uniformly, and also uniformity of a charged state of each toner particle is improved. |
