Patent number: 10148838Abstract: An image forming apparatus includes a non-volatile memory and a processor. The processor obtains first data stored in the non-volatile memory at a predetermined point in time from when startup of a system starts to when the startup finishes before a shut-off command is given. The processor determines progress of predetermined processing in response to a connection command to turn on the power given during the time. When the progress exceeds a predetermined standard, the processor starts continues obtaining second data which is greater than the first data and is stored in the non-volatile memory at a point in time when the startup finishes. After the system finishes, if obtaining the second data is finished, the processor starts up the system by using the second data. Otherwise, the processor starts up the system by using the first data.Type: GrantFiled: July 3, 2017Date of Patent: December 4, 2018Assignee: Konica Minolta, Inc.Inventor: Hirofumi Hashimoto
