A color image forming apparatus and method includes a plurality of recording medium arranged along a conveying path for forming electrostatic latent images, a plurality of developing units installed respectively in the neighborhood of the plurality of recording medium for feeding developers having different lightness to the respective electrostatic latent images formed on the plurality of recording medium and forming developed images a plurality of transfer units for multiple-transferring the developed images formed respectively on the plurality of recording medium sequentially on a material to be transferred which is conveyed along the conveying path, and a plurality of collectors for collecting the respective residual developers on the plurality of recording medium after passing the transfer units in the plurality of developing units respectively. Among the plurality of developing units, the developing unit having the developer with lowest lightness compared with the developing unit having the developer with highest lightness are sequentially installed in the neighborhood of the recording medium from an upstream side to a downstream side of the conveying path.
