A process cartridge is detachably mountable to both of an image forming apparatus of the electrode-rod-detection type and an image forming apparatus of the electrode-plate-detection type. The process cartridge has a photosensitive drum, a developing roller for developing an electrostatic latent image formed on the photosensitive drum, and a toner containing portion containing therein a toner to be used to develop the electrostatic latent image by the developing roller. The process cartridge further has an antenna rod having one end thereof exposed from a cartridge frame, and first to third electrodes including electrode plates. As a result, the process cartridge has the ability to be detachably mountable to both of the main body of the image forming apparatus of the electrode-rod-detection type and the main body of the image forming apparatus of the electrode-plate-detection type. |
