Abstract
A process kit has at least part of image forming structure and is detachably mounted in the main body of an image forming apparatus, and an image forming apparatus using the process kit. Signal sources are disposed on the process kit in accordance with the functional purpose of the process kit. When a process kit is mounted in the main body of the image forming apparatus, the type or property of this process kit is automatically indicated at an indicator section of the main body, thus preventing erroneous use of an undesired process kit. The signal sources not only indicate the functional purpose of the process kit currently mounted in the main body but also automatically set image forming conditions which differ for various kits, thus reproducing high-quality images.
