Beschreibung
Zusammenfassung:	A temperature control method includes: a step of obtaining, by means of PID control, a first energization rate based on a first temperature difference between an actually measured temperature and a target temperature; a step of obtaining a second energization rate based on a second temperature difference between the ambient temperature of the environment in which a heating barrel is disposed and the target temperature; a step of obtaining a corrected energization rate on the basis of the result of comparison of the first energization rate and the second energization rate; and a step of controlling the electrical power to be supplied to a heater on the basis of the corrected energization rate. The corrected energization rate is set to any of predetermined first, second, and third conditions on the basis of the comparison result.
