An image forming apparatus for forming an image on a recording material, includes: a cartridge, detachably mountable to a main assembly of the image forming apparatus, including a memory and an image forming process member actable on an image bearing member in an image forming process; and an image density measuring portion, provided in the main assembly, for measuring a density of a developer image formed by the image forming process. The memory stores information for discriminating a state of the image forming process member on the basis of the density, measured by the image density measuring portion, of the developer image formed under an image forming condition different from that during normal image formation.
