Abstract
An image forming apparatus includes a plurality of cartridges each having an image bearing member and a developer bearing member, an intermediate transfer member onto which developer images are transferred; a detection unit for outputting information related to reflected light from the developer images on the intermediate transfer member; and a control unit. The plurality of cartridges can be simultaneously installed. Each of the plurality of cartridges has a lifespan. The control unit executes image density control on the basis of a value of image data and the information related to the reflected light, and increases execution frequency of the image density control in a case where a first cartridge having a first lifespan and a second cartridge having a second lifespan different from the first lifespan are simultaneously installed.
