Patent number: 7496311Abstract: When a fixing roller 1 generates heat by a magnetic flux generating section 3 during a standby time, a control section 5 rotates the fixing roller 1. This prevents the fixing roller 1 from locally generating heat and being damaged. Moreover, the control section 5 rotates and heats a pressure roller 2 during the standby time, which makes it possible to keep the pressure roller 2 at a specified temperature and to reduce a time taken for a fixing device to recover from the standby state.Type: GrantFiled: June 1, 2006Date of Patent: February 24, 2009Assignee: Konica Minolta Business Technologies, Inc.Inventors: Yasuhiro Ohno, Tomihiko Masuda, Yuji Kamoda, Haruo Iwahashi

Publication number: 20080019742Abstract: In a fixing device, a magnetic flux generated by a coil passes through a magnetic circuit made of a heat generating layer of a fixing member and a magnetic substance core. The magnetic substance core includes a plurality of main cores each having an elongated form along a circumferential direction of the fixing member and arrayed at intervals along a width direction of a sheet. The end row main cores have a second shape effectively closer to an outer peripheral face of the fixing member compared to a first shape possessed by the central row main cores so as to enhance density of the magnetic flux, which passes the magnetic circuit, more in end sections than in a central section with respect to width direction of the sheet.Type: ApplicationFiled: January 30, 2007Publication date: January 24, 2008Applicant: KONICA MINOLTA BUSINESS TECHNOLOGIES, INC.Inventor: Yasuhiro Ohno
