1. A method of updating a boot image for fast booting of an image forming apparatus, the method comprising:
- receiving a new version of firmware to update a previous version of firmware installed in the image forming apparatus;
determining whether the received new version of firmware includes a new version of a second boot image for the fast booting to update a previous version of a first boot image for the fast booting stored in a non-volatile memory; and
if the received new version of firmware includes the second boot image, updating the boot image by controlling the stored first boot image to be replaced with the second boot image,wherein each of the first boot image and the second boot image for the fast booting corresponds to an image file including data of a system state in a process of booting a system of the image forming apparatus,wherein, in a boot image generation mode in the image forming apparatus, the new version of the second boot image is generated by initializing an executed application including selectively initializing data and threads of the executed application which cannot be changed by any user before generation of the new version of the second boot image, andwherein, in a normal booting mode in the image forming apparatus, initializing the executed application and completing the normal booting mode without generating the new version of the second boot image.

Abstract
An image forming apparatus for updating a boot image for fast booting includes an interface unit to receive a new version of firmware to update a previous version of firmware installed in the image forming apparatus, a non-volatile memory to store a first boot image that is a previous version for the fast booting, and a processor updating a boot image by controlling the stored first boot image to be replaced with a second boot image that is a new version when the received new version of firmware includes the second boot image.
