Abstract
An image forming apparatus includes a solid state drive (SSD) that stores information, a Serial Advanced Technology Attachment (SATA) controller that reads information from the SSD, writes information to the SSD, and transmits a device sleep (DEVSLP) signal for shifting the SSD to a DEVSLP state, and a power source control unit that can stop power to the SATA controller and transmits the DEVSLP signal for shifting the SSD to the DEVSLP state during a period in which the power to the SATA controller is stopped.
