摘要：
A disclosed feed control apparatus includes a feed roller; a first detection unit detecting a rotational position of the feed roller; a sensor detecting plural marks arranged on a test chart; a difference calculation unit that calculates a difference between actual and theoretical positional information of a Nth mark when the feed roller rotates one revolution; a correction feeding amount calculation unit that calculates correction feeding amounts of the marks based on the difference and actual feeding amounts of the marks; an error calculation unit that calculates errors between the correction feeding amounts and theoretical feeding amounts by matching them to the corresponding rotational positions of the feeding roller; and a feeding amount control unit that controls the feeding amount based on a relationship between the rotational positions of the feeding roller and the corresponding errors.
