摘要： A heater includes a base, a plurality of heat generators arranged on the base in parallel to a longitudinal direction of the base, a plurality of electrodes on the base, and conductor paths disposed on the base. The conductor paths are electrically connected to the heat generators and the electrodes. The conductor paths include a main conductor path connected to one of the electrodes and a branch conductor path branched from the main conductor path. At least a part of the branch conductor path has a lower electrical resistance per unit length than an electrical resistance per unit length of the main conductor path.

摘要： An image forming apparatus includes a resistive heat generator, a temperature detector, and a power controller that detects a temperature-resistance property of the resistive heat generator before the resistive heat generator is used when the resistive heat generator is removably installed. The power controller obtains power supplied to the resistive heat generator and a change in a temperature of the resistive heat generator, that is detected by the temperature detector, while the power controller supplies the power at a predetermined power duty cycle for adjustment to the resistive heat generator. The power controller calculates the temperature-resistance property of the resistive heat generator based on the power and the change in the temperature that are obtained. The power controller adjusts a power duty cycle at which the power is supplied to the resistive heat generator in use of the resistive heat generator, based on the temperature-resistance property.

摘要： A separator for separating a recording medium from a fixing rotator includes a separation body including a front end and a conveyance path side face. The front end is disposed in proximity to an outer circumferential surface of the fixing rotator. The conveyance path side face faces a conveyance path where the recording medium is conveyed. At least one rotary separation aid projects beyond the conveyance path side face of the separation body toward the conveyance path. The rotary separation aid is rotated by the recording medium as the recording medium comes into contact with the rotary separation aid.

摘要： A fixing device includes a rotatable fuser member a heater, a rotatable pressure member, a thermometer, and a feedback controller. The rotatable fuser member is subjected to heating. The heater heats the fuser member to a heating temperature. The rotatable pressure member is disposed opposite the fuser member. The fuser member and the pressure member are pressed against each other to form a fixing nip therebetween, through which the recording medium is conveyed, so as to fix the toner image in place under heat and pressure. The thermometer is disposed adjacent to the pressure member to detect an operational temperature of the pressure member. The feedback controller is operatively connected with the thermometer to control the heating temperature according to the detected operational temperature, so that the recording medium exhibits a substantially constant post-fixing temperature downstream from the fixing nip regardless of the heat capacity of the recording medium.
