Abstract
A cartridge includes at least a developing device and is detachably mountable to an image forming apparatus. The image forming apparatus includes an image controller for adjusting an image on a transferring material either by directly detecting the density of a toner image formed on an image bearing body or by transferring the toner image onto a second image bearing body and detecting a density of the transferred toner image. The cartridge includes a memory storing a correction parameter, which is used to determine how a control parameter of the image controller should be changed in accordance with the degree of wear of the process cartridge.
