A color electrographic recording apparatus is provided to produce on a recording medium a composite color image comprising a plurality of superimposed component images of different colors, e.g., magenta, cyan, yellow and black. The apparatus includes means for transporting the recording medium in opposite directions along a predetermined path through the electrographic recording apparatus, a recording station in the path and having a recording head with electrode means for forming a latent image on the recording medium, control means operative to energize the electrode means to create a latent image on the recording medium, a plurality of developing means adjacent either one side or both sides of the recording station in the path, each of the developing means for developing a latent image produced on the recording medium at the recording station into a corresponding visible component image of a respective color. The transport means is operative to pass a section of the recording medium through the recording station to form a first component latent image followed by its respective color development and reverse the direction of medium transport to permit formation of a next component latent image followed by its respective color development and repeating this process until all component latent images and their respective color development have been completed to form a composite color image. The color electrographic recording apparatus also includes unique registration means associated with the transport of the recording medium and the apparatus control means to form each component latent image so that all the component color images will be superimposed on one another even in spite of any shrinkage or expansion of the medium during its multiple handling and processing by the electrographic recording apparatus.
