Abstract: An image forming apparatus includes a conveyance sensor disposed near a pair of conveyance rollers so as to accurately detect an amount of movement of the recording paper, a conveyance delay determination unit to determine a conveyance delay of the recording paper, and a conveyance control unit to control drive for rollers. The conveyance delay determination unit obtains conveyance delay information from among information detected with the conveyance sensor, or the like, and accelerates a rotational velocity of the pair of paper feed rollers when the conveyance delay quantity exceeds a threshold.
