An image-reading apparatus includes a gain correction processing portion, and a gain setting control portion including a setting portion that sets a gain condition, the gain setting control portion: repeatedly sets the gain condition in the setting portion at predetermined time intervals, and records the set gain condition in the recording portion, in an idling state from when the power supply portion switches to an on state until a reception portion receives a read instruction; stops setting the gain condition in the setting portion in a reading state after the reception portion receives the read instruction; and implements gain correction on electrical signals output from an imaging element in the gain correction processing portion by applying the gain condition recorded in the recording portion just before the reception portion receives the read instruction.
