PURPOSE:To obtain a dichromatic record print of good print quality by prividing a recharging stage behind plural developing means except a final-stage developing means. CONSTITUTION:With regard to a dichromatic recording device, a two-component magnetic brush developing method is applied to the 1st development and a one-component magnetic toner developing method is applied to the 2nd development. Then, the recharging stage which uses a recharger 13 is provided behind the 1st developing device 2. A photoreceptor 1 is charged uniformly over the entire surface by an initial-stage charger 2 firstly and the exposure of a picture corresponding to red is carried out by an exposing part 3. Then, red toner charged positively is used to perform development at a developing bias voltage setting part 5 and the recharger 13 recharges the photoreceptor 1; and the exposure of the picture corresponding to black is carried out by an exposing part 6 and development is performed by a developing bias voltage setting part 8. |
