Abstract
A control unit controls power to be supplied to a common power supply path in a first period, using a selected first temperature detection member, and controls power to be supplied to the common power supply path in a second period, using a selected second temperature detection member. The first temperature detection member has a higher detected temperature than that of the second temperature detection member, and in the second period, the first detected temperature and the second detected temperature fall within a temperature range between a first temperature and a second temperature lower than the first temperature.
