Abstract
Upon completing a preparation operation including different processes, an image formation apparatus shifts to ready state in which image formation is executable, the processes including at least one process executed using a corresponding motor. The image formation apparatus comprises: an obtainer for obtaining, for each process, an estimated time period between start and completion thereof; and a controller for starting execution of, out of the processes, (i) one process whose estimated time period is the longest, then (ii) any other process so that any other process is executed in parallel with said one process. When said one process is included in the at least one process, the controller initiates the motor by high-speed initiation by applying thereto first voltage that is higher than second voltage. When any other process is included in the at least one process, the controller initiates the motor by normal initiation by applying thereto first voltage.
