Patent ID: 7801454

Claim:
An image formation apparatus that includes at least one motor, executes a preparation operation including a plurality of different processes, and upon completion of the preparation operation, shifts to a ready state in which an image formation operation is executable, the plurality of different processes including at least one process that is executed by driving a corresponding motor of the at least one motor, the image formation apparatus comprising: an obtainer operable to obtain, for each of the different processes, an estimated time period required between a start and completion of the process; and a controller operable to start execution of, out of the different processes, (i) a process whose estimated time period is longer than the estimated time period of any other process, and thereafter, (ii) the any other process so that the any other process is executed in parallel with the process that has been started, wherein when the process to be started first is included in the at least one process, the controller initiates the corresponding motor by a high-speed initiation by applying thereto a first voltage that is higher than a second voltage, and when the any other process is included in the at least one process, the controller initiates the corresponding motor by a normal initiation by applying thereto the second voltage.
