Abstract: An image forming apparatus includes an induced voltage detection portion configured to detect an induced voltage Vk in a motor; and an engagement/disengagement completion time detection portion configured to detect an engagement completion time and a disengagement completion time based on the induced voltage Vk detected by the induced voltage detection portion. The engagement completion time is a time at which engagement of a clutch is actually completed. The disengagement completion time is a time at which disengagement of the clutch is actually completed. A control portion determines a command timing based on any one of the engagement completion time and the disengagement completion time detected by the engagement/disengagement completion time detection portion, the command timing being a time at which a command is given to the clutch to perform an engaging operation or a disengaging operation.
