20140314442 | Method for Remanufacturing Toner Cartridges - A method for remanufacturing toner cartridges includes the use of a plurality of machine screw inserts. Each of a plurality of screw holes of a toner cartridge shell is tapped to create new threading within the plurality of screw holes. The plurality of machine screw inserts is positioned into the plurality of screw holes in order to reinforce the plurality of screw holes, wherein each of the plurality of machine screw inserts has a threaded outer surface and a threaded inner surface. The plurality of machine screw inserts provides a durable interface with a plurality of screws that reduces the chance of failure of the plurality of screws as the plurality of screws is positioned within the plurality of screw holes. An adhesive is applied to each of the plurality of machine screw inserts in order to secure the plurality of machine screw inserts within the plurality of screw holes. | 2014-10-23 |
20140314443 | APPARATUS AND METHOD FOR PREVENTING AN INFORMATION STORAGE DEVICE FROM FALLING FROM A REMOVABLE DEVICE - An information storage device installed in a removable device configured to be removably installed in an image forming apparatus body, includes: an information storage unit that stores information communicated between the image forming apparatus body and the removable device; a terminal that comes in contact with a body side terminal; and a substrate that holds the information storage unit and the terminal and includes a hole configured to be engaged with a protruding section installed in the image forming apparatus body. The terminal includes a plurality of terminals each including one of a plurality of metallic plates arranged in a transverse direction thereof. An earth terminal, which comes in contact with a body side earth terminal formed in the protruding section, is formed in the hole. The hole is disposed at a position sandwiched between two metallic plates among the plurality of metallic plates. | 2014-10-23 |
20140314444 | INTERVAL SECURING MEMBER, DEVELOPING APPARATUS, AND PROCESS CARTRIDGE - An interval securing member configured to maintain a distance between an image bearing member and a developer bearing member includes a first image bearing member side contact portion that contacts with the image bearing member upstream in a rotation direction of the image bearing member from a nearest position where the distance between the image bearing member and the developer bearing member becomes the smallest, a first developing side contact portion that contacts with the developer bearing member upstream from the nearest position in a rotation direction of the developer bearing member, a second image bearing member side contact portion that contacts with the image bearing member downstream from the nearest position in the rotation direction of the image bearing member, and a second developing side contact portion that contacts with the developer bearing member downstream from the nearest position in the rotation direction of the developer bearing member | 2014-10-23 |
20140314445 | PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes a drum, first and second guidable portions guidable by first and second guides when the cartridge enters or advances in the main assembly, first and second regulatable portions provided at leading and trailing sides of the cartridge with respect to the advancing direction and regulated by a first main assembly regulator when the process is advancing in the main assembly, and first and second positionable portions to be positioned at first and main assembly second positioners, respectively, by the urging force of a main assembly urging member after the first and second regulatable portions pass the first and second regulators, respectively. The cartridge is mounted to the main assembly with the first and second positionable portions at the first and second positioners, respectively, by the urging force of the urging member. | 2014-10-23 |
20140314446 | Image Forming Apparatus Including Endless Belt Disposed Above Photosensitive Drum - An image forming apparatus includes a frame, a photosensitive drum, an endless belt disposed above the photosensitive drum, and a pressing member. The photosensitive drum includes a drum body and a flange portion that is provided on one end portion of the drum body. The flange portion has a contacted portion and a pressed portion. The pressing member presses the pressed portion upward to permit the photosensitive drum to be in contact with the endless belt. The frame has a positioning portion disposed above the pressing member and above the photosensitive drum. The positioning portion is configured to be in contact with the contacted portion and to position the photosensitive drum when the pressing member presses the pressed portion. The pressed portion is disposed farther from the drum body in an axial direction of the photosensitive drum than the contacted portion. | 2014-10-23 |
20140314447 | SUPPORTING MECHANISM AND IMAGE FORMING APPARATUS - Disclosed is a supporting mechanism including a bearing support portion that supports a bearing and is open so that the bearing is removed in a first direction that crosses a rotating shaft that is supported by the bearing, a driving shaft coupling that transmits a driving force to the rotating shaft by being connected to a rotating shaft coupling that is provided at one end of the rotating shaft, and a contact member that includes a bearing contact portion that makes contact with the bearing. | 2014-10-23 |
