Abstract
In an image forming apparatus, a latent image electrostatically formed on a photoconductive element is developed by a two-ingredient type developer consisting of toner and carrier. The photoconductive element has a life coincident with the life of the developer. When the photoconductive element and developer reach the end of their life, they are replaced at the same time.
