Color image forming system and method of forming color image using the system

A method of forming a color image comprising:

• preparing a photosensitive body, a charger which charges the photosensitive drum, a laser scanning unit which radiates light onto the charged photosensitive body, and forms an electrostatic latent image thereon, a plurality of developing units respectively having toners having colors of cyan, magenta, yellow, and black, arranged along an outer surface of the photosensitive body, to develop the electrostatic latent image with the toner, a transfer unit which transfers the developed image onto a recording medium, and a fusing unit which fuses the transferred image onto the recording medium;
• developing a plurality of monochromatic images using the developing units and overlapping the monochromatic images on the transfer unit to produce a full color image;
• transferring the full color image onto the recording medium using the transfer unit;
• and
• fusing the transferred image onto the recording medium using the fusing unit,
• wherein the developing units are arranged based on the respective toner colors in the order of cyan, magenta, yellow, and black from the laser scanning unit in a traveling direction of the outer surface of the photosensitive body, and the developing is performed in the order of yellow, magenta, cyan, and black.
