Publication number: 20110305482Abstract: 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.Type: ApplicationFiled: March 19, 2010Publication date: December 15, 2011Applicant: PRINT-RITE UNICORN IMAGE PRODUCTS CO., LTD.

Patent number: 7101022Abstract: An attachable and detachable continuously supplying ink container comprises two or more shell bodies that are separated from each other and substantially sealed. Each shell body is provided with an ink filling port having a cap, an air filter and an ink outlet port. Each shell body may form a continuously supplying ink container after it has been filled with ink. The ink container can supply ink to a corresponding print head or cartridge by means of a tube being connected with its ink outlet port. Each shell body of the ink continuously supplying container is provided with a connecting part for connecting an adjacent shell body of the continuously supplying ink container. Several shell bodies may be connected to each other and form a unit via the connecting parts. Accordingly, this provides convenience of use and a reduction of manufacturing cost and user cost.Type: GrantFiled: October 13, 2004Date of Patent: September 5, 2006Assignee: Print-Rite.
