    • An image forming apparatus and method in which the flow of a toner image formed on an image carrier is prevented at the time of removing a surplus liquid developer and at the time of transfer of the image onto a transfer material. The apparatus includes an image carrier, a device for forming an electrostatic latent image on a surface of the image carrier, and a developing section for supplying a liquid developer onto the electrostatic latent image so as to form a toner image. The apparatus also includes a device for removing a surplus liquid developer remaining on the surface of the image carrier after the toner image is formed. A transfer device transfers the toner image onto a surface of a transfer material. An electric charge giving device, which is disposed between the developing section and the device for removing the surplus liquid developer, applies an electric charge to the toner image in a same polarity as that of the toner image.
    • 一种图像形成装置和方法,其中在去除多余的液体显影剂时和在将图像转印到转印材料上时,防止在图像载体上形成的调色剂图像的流动。 该装置包括图像载体,用于在图像载体的表面上形成静电潜像的装置和用于将液体显影剂供应到静电潜像上以形成调色剂图像的显影部分。 所述设备还包括用于在形成调色剂图像之后去除残留在图像载体表面上的剩余液体显影剂的装置。 转印装置将调色剂图像转印到转印材料的表面上。 设置在显影部分和用于除去剩余液体显影剂的装置之间的电荷给予装置以与调色剂图像相同的极性向调色剂图像施加电荷。

    • A developing device for an electrographic printing apparatus provided has stable performance and improved printing quality. The developing device (5) for the electrographic printing apparatus (1) includes a supplying channel (37) having at least one stirring/delivering roller (27) for stirring and delivering a carrier and a toner charged by contacting the carrier; a developing roller (25) for supplying the toner adhered to the carrier to a supplying position of an electrostatic latent image on the photoreceptor (3), the developing member being disposed on a photoreceptor side of the supplying channel (37) and having a outer surface (47) that moves circumferentially and attracts the carrier; a collecting unit for collecting the carrier from the outer surface (47) at a position downstream of the supplying position in the moving direction of the outer surface (47); a collecting channel (39) for delivering the carrier collected at the collecting unit and circulating and supplying the carrier to the supplying channel (37); and a toner-concentration adjusting device (35), provided in the collecting channel (39), for adjusting the ratio of the carrier and the toner delivered through the collecting channel (39) to a predetermined value.
