、原稿の二色に対応する静電潜像を形成し、この潜像を
１回の現像により可視化する二色り像装置において、 現像剤に２種のキャリヤと２色のトナーとからなるもの
を用い、第１のキャリヤについては第１の着色トナーの
第２の着色トナーを異極性に帯電させ、第２のキャリヤ
については第１の着色トナーと第２の着色トナーを同極
性に帯電させる材料としたことを特徴とする二色現像装
置。[Claims for Utility Model Registration] Electrostatic latent images are formed on an electrostatic latent image forming body, corresponding to the two colors of the document, which have mutually different polarities with respect to the background, and these latent images are In a two-color image device that visualizes by development, a developer consisting of two types of carriers and two color toners is used, and for the first carrier, the second colored toner of the first colored toner is of a different polarity. A two-color developing device characterized in that the second carrier is made of a material that charges the first colored toner and the second colored toner to the same polarity.
