摘要：
An image forming apparatus includes an image bearing member; a developing device for developing a latent image formed on the image bearing member, the image bearing member and the developing means being detachably mountable to the apparatus as a process unit; a developer supply unit for supplying a developer to the developing means, the developer supply unit being detachably mountable to the apparatus; and a first memory mounted on the process unit. The first memory stores information relating to the developer supply unit.
