    • An image forming method wherein a latent image is formed by subjecting an image retainer having a photoconductive layer to a image exposure, a toner image is formed by developing the latent image with a toner, each the step of forming the latent image and the step of forming the toner image are repeated at least one time, and a plurality of toner images formed on the image retainer to a transfer material. At least one of the toner images is formed with a toner which has a spectral transmissivity as to substantially absorb a visible light but transmit a light having a wavelength of 750 nm or more. The latent image is formed by subjecting the image retainer bearing the toner image to an image exposure with a light containing a wavelength component of 750 nm or more.

    • A color image forming apparatus including a color image reader for optically scanning a document to produce blue, green, and red color separated information, a processor for processing the color separating information supplied by the reader and generating black, yellow, magenta, and cyan color information signals, a rotatable image retainer, and two latent image forming devices for forming latent images at a common region on the image retainer in accordance with the color information signals corresponding to two recording colors. The first latent image is formed by one of the latent image forming devices in synchronization with the scanning of the color image recorder to form a first latent image at a first writing position. The second latent image forming device is delayed to form the second latent image at a second writing position. The delay device compensates for the time necessary for the common region on the image retainer to travel between the first and second writing positions. The apparatus further includes a number of developers, each developer being used to develop one of the latent images, thereby forming a multicolor image composed of multiple toner images on the image retainer. Two color latent images, corresponding to two of the color information signals, are formed on the image retainer and developed by the developing means during the first rotation of the image retainer corresponding to a first optical scanning of the document, and the remaining two color latent images, corresponding to the remaining two color information signals are formed on the image retainer and developed by the developing devices during a second rotation of the image retainer corresponding to a second scanning of the document. All the toner images are then simultaneously transferred to the transfer sheet.
    • 一种彩色图像形成装置,包括用于光学扫描文档以产生蓝色,绿色和红色分离信息的彩色图像读取器,用于处理由读取器提供的颜色分离信息并产生黑色,黄色,品红色和青色的处理器 信息信号,可旋转图像保持器和用于根据对应于两个记录颜色的颜色信息信号在图像保持器上的公共区域处形成潜像的两个潜像形成装置。 第一潜像由潜像形成装置之一与彩色图像记录器的扫描同步地形成,以在第一写入位置形成第一潜像。 第二潜像形成装置被延迟以在第二写入位置形成第二潜像。 延迟装置补偿图像保持器上的公共区域在第一和第二写入位置之间行进所需的时间。 该装置还包括多个显影剂,每个显影剂用于显影潜像中的一个,从而在图像保持器上形成由多个调色剂图像组成的多色图像。 对应于两个颜色信息信号的两个彩色潜像被形成在图像保持器上,并且在对应于原稿的第一光学扫描的图像保持器的第一次旋转期间由显影装置显影,并且剩余的两个颜色潜像 对应于剩余的两个颜色信息信号的图像形成在图像保持器上,并且在对应于文档的第二次扫描的图像保持器的第二次旋转期间由显影装置显影。 然后将所有调色剂图像同时转印到转印纸上。
