Abstract
A driver includes: a first motor located so as to rotate a driving shaft; a second motor located so as to rotate the driving shaft; and circuitry. The circuitry performs control while switching between a dual mode and a single mode. In the dual mode, the circuitry drives the first motor and the second motor together. In the single mode, the circuitry drives a drive target motor that is one of the first motor and the second motor and performs such control as to set one or more among a rotational speed, rotation acceleration, and rotation deceleration of the drive target motor to be lower than that or those in the dual mode.
