ABSTRACT:
A color image recording apparatus for recording a color image of an original document on a photosensitive paper using at least yellow, magenta and cyan liquid toners respectively containing yellow, magenta and cyan color materials as primary color components. At least one of the three liquid toners contains foreign color materials which are the primary color components of the rest of two liquid toners. To reproduce the color image of the original document with maximum possible fidelity, a disk-shaped rotary filter is provided for receiving imaging light separated into blue, green and red light components and changing light transmission rates passing through the filter so as to be equal to the proportion of the color material to be reproduced which is contained in the yellow, magenta and cyan liquid toners. The light transmission rates are changed each time when one of the yellow, magenta and cyan liquid toners is used.
