摘要： 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.
