Claim of US Patent No. 9,563,444

1. An image forming apparatus to which a device is connectable, comprising:
a processor; and
a memory storing instructions which, when executed by the processor, cause the image forming apparatus to function as:
a creation unit configured to create a hibernation image based on data stored in a memory of the image forming apparatus;
a first obtaining unit configured to obtain a first device connection state indicating a device connection state at a timing
of turning off the image forming apparatus;

a second obtaining unit configured to obtain a second device connection state indicating a device connection state at a timing
of turning on the image forming apparatus; and

a control unit configured to start the image forming apparatus by using the hibernation image, in a case that the second device
connection state corresponds to the first device connection state, and start the image forming apparatus without a hibernation
image, in a case that the second device connection state does not correspond to the first device connection state.
