Abstract
An image forming apparatus can switch between a color mode, in which an image is formed by sequentially transferring color toner images formed by developing members in an overlapping manner, and a mono mode, in which an image is formed by using one developing member. The developing member used in the mono mode develops the toner image to be transferred secondly or thereafter in the color mode, an exposure device exposes a non-image portion where the toner image is not formed on the surface of an image carrier at an exposure amount smaller than an exposure amount for an image portion where the toner image is formed, and, in the mono mode, the exposure amount at which the exposure device exposes the non-image portion of the image carrier in the case the image is formed in the mono mode is smaller than the color mode.
