Abstract
An image forming apparatus includes a developing device for developing an electrostatic latent image, formed on an image-bearing member, with toner; a developer supply container which contains developer containing toner and a carrier and is detachably mountable to a main assembly of the image forming apparatus; developer supply means for supplying the developer contained in the developer supply container to the developing device; and developer discharge means for permitting discharge of the developer in the developing device to the outside of the developing device. To the image forming apparatus, one of plural kinds of developer supply containers containing developers having different carrier ratios in the developers is selectively mountable. The image forming apparatus further comprises notification means for providing notification of the kind of the developer supply container to be selected on the basis of information on deterioration of the carrier when the developer supply container is replaced.
