Abstract
A heating device includes a heat applying member heated by a heat source, a pressure applying member pressure contacting the heat applying member with a prescribed pressure, and a temperature detection device that detects temperature of the heat applying member. A timing device is provided to count time elapsing from when the heat source starts heating the heat-applying member. A control device is provided to determine that heat application as a start up operation to the heating member is completed when the temperature detected by the temperature detection device reaches a prescribed threshold and the elapsing time counted by the timing device reaches a prescribed threshold.
