PURPOSE:To develop an electric and magnetic latent image on a recording body uniformly, with high density and at a high speed, by rotating a magnetic roll in a non-magnetic sleeve to carry a magnetic toner layer, and to generate powder smoke of a magnetic toner from the side end part of a magnetic member. CONSTITUTION:When a recording drum 7 which has formed a charge latent image on the surface is rotated clockwise, and a magnetic roll 3 is rotated clockwise, a magnetic toner 5 moves counter-clockwise in a layer state on the surface of a sleeve 1. Subsequently, a toner layer 5A forms a powder smoke layer 5B scattered out in the diameter direction in the side end part of a magnetic plate 8, operates on the surface of the drum 7, and an electrostatic latent image is developed. |
