Abstract: An electronic device includes a first CPU, a second CPU, an auxiliary storage unit, and a controller. The auxiliary storage unit includes a first starting program for the first CPU and a second starting program for the second CPU. The first CPU loads the first starting program via the controller, and causes the controller to load the second starting program in DMA transfer. The controller, if the controller is caused by the first CPU to transfer part of the first starting program while the controller is loading the second starting program, stops loading the second starting program. When completing the transfer of the part of the first starting program, the controller restarts loading the second starting program.

Abstract: An image forming apparatus includes a main control unit, a sub control unit, a main storage unit, an auxiliary storage unit, an auxiliary storage load unit, a load-program storage unit, and an external storage load unit. The auxiliary storage load unit is configured to load each of a program to be executed by the main control unit and a program to be executed by the sub control unit stored in the auxiliary storage unit from the auxiliary storage unit to the main storage unit at first activation. The external storage load unit is configured to load the program stored in the external storage medium by the load-program storage unit to the main storage unit at a subsequent activation concurrently with loading the program to be executed by the main control unit from the auxiliary storage unit by the auxiliary storage load unit.
