  • Patent number: 9207607
    Abstract: An image forming apparatus that heat-fixes a toner image onto a recording sheet passing through a fixing nip formed by pressing a pressurizing member against a heating rotational body heated by a heater, comprising: a storage unit storing a basic power consumption level of the heater determined in advance in a situation where inflow of inrush current to the heater is not occurring; an estimation unit calculating an estimated power consumption level of the heater by estimating an increase in the power consumption level, with respect to the basic power consumption level, brought about by inflow of inrush current to the heater; and an output unit outputting the estimated power consumption level. The heater switches between a heating state of receiving power supply and a non-heating state of not receiving power supply. The increase is estimated according to a duration of a non-heating state immediately preceding the heating state.

  • Publication number: 20150256079
    Abstract: An electric power supply control device comprises AC/DC converter, DC/DC converters, and an output electrical voltage monitor unit of the AC/DC converter. When output electrical voltage of the AC/DC converter increases to the first preset value P1, the AC/DC converter stops the convert. When the output electrical voltage decreases to the second preset value P2, the AC/DC converter restarts the convert. The first preset value P1 is equal to or less than the lowest value, out of the upper limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work. The second preset value P2 is more than or equal to the highest value, out of the lower limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work.

  • Patent number: 8971745
    Abstract: An image forming apparatus includes first and second image-forming portions and an intermediate transporting portion. A control unit checks fixing units in the image-forming portions and determines whether or not the fixing unit in the first image-forming portion is a fixing unit for an envelope. If not, the control unit controls a manipulation and display unit to display guidance for urging a user to exchange the first fixing unit. If so, the control unit determines whether or not too fixing unit in the second image-forming portion is a fixing unit for an envelope. If not, the control portion controls a manipulation and display unit to display a guidance for urging a user to exchange the second fixing unit. If both of fixing units in the first and second image-forming portions are fixing units for the envelope, the control unit allows an envelope mode control operation.
