Patent number: 5968418Abstract: The purpose of the present invention is to provide a conductive contact material, the contents of which do not generate soil on a charged body not only during initial use but also after repeated use. A conductive contact material consists of thermoset urethane material containing an antioxidant within a range from 0.1 to 0.3% by weight, and an inorganic ion electrically conducting agent with in a range form 0.01 to 2.00% by weight. After ozone exposure or the like, molecule chain scission of the base material and antioxidant leads generation of active monomers and origomers. However, the conductive contact material containing the above specified proportion of an antioxidant and an inorganic ion electrically conducting agent prevents generation of active monomers and origomers which are soiling source for a charged body. The conductive contact material also prevents antioxidant itself from being a soiling source.Type: GrantFiled: July 10, 1998Date of Patent: October 19, 1999Assignees: Kabushiki Kaisha Inoac Corporation, Minolta Co., Ltd.Inventors: Kouji Matsushita, Ikuro Chimoto, Munenori Nakano, Takeshi Suzuki, Koichiro Higashiguchi

Patent number: 5918086Abstract: Image density is detected by a B/W ratio detection integrator 30 via a video signal 11 from a video controller 40 when an image signal is inputted. When a latent image formed on a photosensitive body 7 in accordance with the image signal is transferred to a transfer material 12 by a transfer charging device 8, a transfer current of the transfer charging device 8 is controlled in a timely fashion by a CPU 20 in accordance with the image density detected from this image signal, thus ensuring optimum transfer efficiency. Even when the environment and printing pattern change for each part of a single-page image, this makes it possible to deal accurately with these changes to ensure stable transfer efficiency and good imaging.Type: GrantFiled: March 23, 1998Date of Patent: June 29, 1999Assignee: Minolta Co., Ltd.Inventors: Munenori Nakano, Kouji Matsushita, Tomohiko Teranishi, Tetsuya Okashita, Mineo Yamamoto

Patent number: 5873013Abstract: A charging member is disposed so as to contact a surface of a charge-receiving member which moves relative to the charging member. In conjunction with the movement of the charge receiving member, the charging member removes foreign substance present on the charge-receiving member on the upstream side in the direction of travel of the charge-receiving member at the contact region with the charging member. Simultaneously, a discharge voltage is applied to the charging member so that the charging member charges the charge-receiving member in the area from which said foreign substance has been removed at the contact region on the downstream side of the charge-receiving member in the direction of travel of the charge-receiving member. During a cleaning operation, the charging member retracts from the charge-receiving member and is out of contact therewith in accordance with the number of image formations, black and white ratio, and humidity.Type: GrantFiled: December 24, 1997Date of Patent: February 16, 1999Assignee: Minolta Co., Ltd.Inventors: Kouji Matsushita, Futoshi Okazaki
