Abstract
A fixing device includes a rotator (), an opposed rotator (), a heater (), a housing (), a resistor (), a separator (), and a biasing member (). The opposed rotator is opposite the rotator. The heater includes a resistive heat generator (). The heater is in direct contact with the inner circumferential surface of the rotator or in contact with the inner circumferential surface of the rotator via a conductive member () to heat the rotator. The housing is conductive and grounded. The resistor is in the housing. The separator is conductive and is in contact with the rotator. The separator is assembled into the housing via the resistor. The biasing member biases the separator against the rotator. The biasing member is assembled into the housing via the resistor.
