A heater inspection apparatus including an applying unit, a current detector, a voltage detector, a temperature detector, a memory, a first calculating unit, a second calculating unit and a finding unit is provided. The applying unit applies an electrical power to a heater based on an AC power source. The current detector detects a current flowing through the heater. The voltage detector detects a voltage applied to the heater. The temperature detector detects a temperature of the heater. A temperature coefficient of resistance is stored in advance on the memory. The first calculating unit and the second calculating unit respectively calculate a resistance of the heater at an inspection time and a reference time. The finding unit finds a deterioration degree of the heater based on results of the first and second calculating units.
