Publication number: 20070189794Abstract: The present invention provides a fixing device and a digital photocopier which can shorten the time from an instruction of starting image formation to end of fixing. The fixing device is provided in a cylinder made of metal and having a small thickness, and includes a magnetic excitation coil. When the power source is turned on, all the electric power defined by subtracting an electric power amount consumed by components other than the fixing device is supplied to the magnetic excitation coil to perform heating. As the structural components of the photocopier and auxiliary devices added to the photocopier operate, the electric power defined by subtracting, from the maximum input electric power, the electric power consumed by the structural components of the photocopier and the auxiliary devices is supplied to perform heating. In this manner, the heat roller of the fixing device is heated, in a short time, to a temperature which enables fixing, so that the time required for first copying can be shortened.Type: ApplicationFiled: April 20, 2007Publication date: August 16, 2007Inventors: Noriyuki Umezawa, Taizo Kimoto, Kenji Takano, Hisaaki Kawano, Hiroshi Nakayama, Osamu Takagi, Satoshi Kinouchi, Kazuhiko Kikuchi, Masahiko Ogura

Patent number: 7162175Abstract: A fixing device for an image forming apparatus includes a heating roller and a press roller. The press roller is pressed against the heating roller, and the heating roller and the press roller operate to fix an image on a document. The fixing device also includes a heat source that heats the heating roller. The heat source is configured to activate to heat the heating roller substantially when the heating roller and the press roller start to rotate, independent of a temperature of the heating roller.Type: GrantFiled: November 29, 2004Date of Patent: January 9, 2007Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Noriyuki Umezawa

Patent number: 7136602Abstract: If, in a standby state, no operation is executed for a control panel (11) or ADF (13) before the elapse of a predetermined time measured by a timer (12), the set temperature of a fixer (20) is reduced. After that, if an operation of for the control panel (11) or ADF (13) is executed, the set temperature of the fixer (20) is raised. The set temperature at this time is higher than the fixing temperature in the normal standby state. When the set temperature of the fixer (20) is set to be higher than that in the normal standby state to temporarily increase the heat amount of the fixer (20), the heat amount is hardly absorbed by transfer paper sheets at the time of copy. In addition, since the fixing power increases, the time until a fixing set temperature is obtained can be shortened. Accordingly, power consumption can be reduced without any decrease in operability, productivity, and copy quality.Type: GrantFiled: July 14, 2004Date of Patent: November 14, 2006Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Noriyuki Umezawa

Patent number: RE40058Abstract: A method and apparatus for discriminating bottle types, for stirring the toner, and for detecting the amount of toner remaining in the toner bottle. A toner bottle is adapted to fit the apparatus for discriminating toner bottle types, and a toner bottle is adapted for the apparatus for stirring toner. The genuineness of the toner bottle product is checked by sensing a rib assumed to be formed with a predetermined length on the outer surface of the toner bottle. Toner is stirred by continuously rotating the toner bottle in forward and reverse directions. The toner bottle can be easily rotated in the forward and reverse directions by sensing the rib of the toner bottle by using the sensor. Since the load of rotation of the toner bottle changes in accordance with the amount of remaining toner, the rotational speed of the toner bottle is sensed by using the sensor to check whether toner is close to empty.Type: GrantFiled: September 10, 2003Date of Patent: February 12, 2008Assignee: Toshiba Tec Kabushiki KaishaInventors: Noriyuki Umezawa, Takayuki Nishi, Yoshiharu Taniyama, Shinichi Itoh
