Abstract
An image forming apparatus includes: a plurality of image forming units each with an image carrier on which an electrostatic latent image is formed, and each with a developing member for developing process on the electrostatic latent image, wherein the image forming apparatus superimposes toner images of the respective colors to form a composite color image; when images on a plurality of pages are formed, the developing members of the respective colors are started or stopped in response to presence or absence of latent images of the respective colors on a page that is targeted for image formation; and when the image forming unit starts to be driven, a developing member, corresponding to a color whose latent image is not to be formed on a first page of the plurality of pages, is not started.
