Abstract
A color image forming apparatus includes one image bearing member, an image forming unit configured to successively form images with toners in plural different colors on the image bearing member per color, a revolving intermediate transfer member, and a transfer unit configured to successively transfer the images on the image bearing member onto the intermediate transfer member in a superimposed relation in a transfer section. Images are transferred in a superimposed relation by executing control such that, when formation of the next image is not started at a due timing of starting the formation of the next image, a timing at which transfer is started after the formation of the next image and a timing at which a leading end of the previously transferred image reaches the transfer section are matched with each other by temporarily changing the revolving speed of the intermediate transfer member or stopping it.
