Abstract
A process cartridge used in an image forming apparatus, the process cartridge having a photosensitive drum, a developer roller, a conductive electrode and a rectifier. The photosensitive drum and the developer roller are contacted with each other. The conductive electrode is contacted with a power supply electrode in the image forming apparatus to receive a developing bias. The rectifier converts an alternating current bias voltage into a direct current bias voltage. The rectifier is electrically connected between the conductive electrode and the developer roller. A rectifier converting an alternating current bias voltage into a direct current bias voltage is added into a contact process cartridge in the present invention. Therefore, the contact process cartridge can be applied to a printer using a jumping development method.
