Abstract:
1. A fixing device, comprising: a fixing member to melt a toner image to fix the toner image to a recording medium; a pressing member pressed against the fixing member to form a nip to where the recording medium is conveyed; a fixing member temperature detector provided to detect the temperature of the fixing member; multiple pressing member temperature detectors provided to detect a temperature at multiple positions in a width direction of the pressing member in a width direction thereof; a heating member comprising a heating layer to heat the fixing member, wherein an amount of power supplied to the heating member is controlled based on a result detected by the fixing member temperature detector; an exciting coil provided opposite the heating member to generate magnetic fluxes to inductively heat the heating layer using the magnetic fluxes; and one or more pairs of degaussing coils provided opposite the exciting coil at both edges of the fixing member in a width direction thereof to generate magnetic fluxes at both edges of the fixing member to degauss the magnetic fluxes generated by the exciting coil, wherein an amount of power supplied to the one or more pairs of degaussing coils is controlled based on a result detected by each of the multiple pressing member temperature detectors.
