Abstract:
A heater includes a plurality of resistive heat generators electrically connected to each other in parallel. A power supply supplies power to the resistive heat generators. An electric current detector detects an electric current that flows through the resistive heat generators. A voltage detector detects a voltage applied to the resistive heat generators. An electric current controller controls the electric current that flows through the resistive heat generators based on the electric current detected by the electric current detector and the voltage detected by the voltage detector. The electric current detector detects the electric current in a state in which, after the power supply starts supplying the power to the resistive heat generators, an identical waveform of an alternating current supplied to the resistive heat generators continues for a predetermined time period or longer taken for the electric current detector to detect the electric current.

Claim (Index 14):
An image forming apparatus comprising:\n an image forming device to form an image with a developer; and a fixing device to fix the image on a recording medium, the fixing device including:\n a tubular belt that is rotatable; \n a pressure rotator to contact the tubular belt, \n at least one of the tubular belt and the pressure rotator to define a fixing nip through which the recording medium bearing the image is conveyed; and \n a heater to heat the tubular belt from which heat is conducted to the fixing nip, \n the heater including:\n a base; \n a plurality of resistive heat generators electrically connected to each other in parallel in a longitudinal direction of the base; \n a power supply to supply power to the resistive heat generators; \n an electric current detector to detect an electric current that flows through the resistive heat generators; \n a voltage detector to detect a voltage applied to the resistive heat generators; and \n an electric current controller to control the electric current that flows through the resistive heat generators based on the electric current detected by the electric current detector and the voltage detected by the voltage detector, \n the electric current detector to detect the electric current in a state in which, after the power supply starts supplying the power to the resistive heat generators, an identical waveform of an alternating current supplied to the resistive heat generators continues for a predetermined time period or longer taken for the electric current detector to detect the electric current.
