Abstract:
An image forming apparatus which has a hibernation function and is capable of selecting a suitable startup method even in a case where device connection states are different at power-off and at next startup. A hibernation image created based on data stored in a memory of the image forming apparatus and a first device connection state indicative of whether the device is connected to the image forming apparatus are stored in a flash disk. After that, when power to the image forming apparatus is turned off and the power is turned on again, a second device connection state indicative of whether the device is connected to the image forming apparatus is obtained. When the first and second connection states are different, the image forming apparatus is started without using the hibernation image, and when they are the same, the image forming apparatus is started using the hibernation image.
