Abstract
PURPOSE: To achieve the improvement in the sharpness of recording images of two colors by providing a roller applied with the charge of the polarity opposite from that of a two-component type developer on its surface near the surface of a sleeve and removing the two component type developer mixed from a magnetic power layer.
CONSTITUTION: Developing parts 6, 12 which respectively develop the electrostatic latent images formed on a recording medium 1 by a two-component developer 7 and a magnetic toner 13 of a color differing from this are provided. At the time when a magnetic toner layer 22 contacts the surface of the recording medium 1 in the developing part 12, apart of the two-component developer 7 stuck on the recording medium 1 comes off and mixes into the magnetic toner layer 22. A roller 23 applied with the charge of the polarity opposite from that of the two component type developer 7 on its surface is provided in proximity to the lower side of a sleeve 19 in order to remove the two component developer 7a having entered the magnetic toner layer 22 from said layer. The two component developer 7 and the magnetic toner 13 separated in this way are recovered and are again used for development, thus the sharp two-color imges may be obtained.
