Abstract
A multi-color image forming apparatus, method and computer program product storing computer instructions, wherein color information latent images corresponding to respective colors and color patch latent images corresponding to respective colors are formed on a first image bearing member, the color information and patch latent images formed on the first image being member are developed with respectively colored toners so as to form respective color toner images and color toner patches, and the color toner images and color toner patches are transferred from the first image bearing member onto a second image bearing member. The density of toner used in developing the color information and patch latent images is controlled in relation to the color toner patches. Latent image forming, developing, and transferring are controlled such that color toner images of different toner colors are transferred superimposed onto the second image bearing member, and color toner patches are transferred not superimposed onto the second image bearing member. Upon completion of formation of the superimposed color toner images of a multi-color original image, the superimposed color toner images are transf…
