    • This apparatus comprises a photosensitive drum; exposing means for forming a plurality of electrostatic latent images on the photosensitive drum one after another in accordance with the color-separated printing information; means for developing the electrostatic latent images on the photosensitive drum one after another by toners having the hues corresponding to the color-separated printing information to turn them into toner images; and intermediate transfer medium which is pressed to the photosensitive drum so that the toner image on the photosensitive drum is transferred to it one after another and a multi-color toner image is formed on it; means to transport a recording medium to and from the intermediate transfer medium in order to transfer and fix the multi-color toner image formed on the intermediate transfer medium to the recording medium; and a thermally fixing means which is pressed to the intermediate transfer medium through the recording medium. A plurality of electrostatic latent images in yellow, magenta, cyan, and black in that order are formed on the photosensitive drum in accordance with the printing information separated for yellow, magenta, cyan, and black. The electrostatic latent images are developed by use of toners having hues corresponding to the color-separated printing information in order to form the yellow, magenta, cyan, and black images in that order. The respective color toner images are transferred to the intermediate transfer medium sequentially in the order of yellow, magenta, cyan, and black to form a multi-colored toner image on the intermediate transfer medium. This multi-color toner image is transferred and fixed to the recording medium.
    • 该装置包括感光鼓; 曝光装置,用于根据分色打印信息一个接一个地在感光鼓上形成多个静电潜像; 用于通过具有对应于分色打印信息的色相的调色剂将感光鼓上的静电潜像显影以将其转变为调色剂图像的装置; 和中间转印介质,其被压到感光鼓上,使得感光鼓上的调色剂图像一个接一个地转印到其上,并且在其上形成多色调色剂图像; 用于将记录介质输送到中间转印介质和从中间转印介质传送记录介质以便将形成在中间转印介质上的多色调色剂图像转印并固定到记录介质上的装置; 以及热固定装置,其通过记录介质被压到中间转印介质上。 根据黄色,品红色,青色和黑色分开的打印信息,在感光鼓上形成多个静电潜像,分别为黄色,品红色,青色和黑色。 通过使用具有对应于分色打印信息的色调的调色剂来显影静电潜像,以便按顺序形成黄色,品红色,青色和黑色图像。 相应的彩色调色剂图像按黄色,品红色,青色和黑色的顺序依次转印到中间转印介质上,以在中间转印介质上形成多色调色剂图像。 这种多色调色剂图像被转印并固定到记录介质上。
