An image recording apparatus includes: a first motor for rotating first and second rollers; a second motor; a recording portion provided downstream of the first roller, the second roller provided downstream of the recording portion; a sensor portion provided between the recording portion and the second roller to sense a sheet; and a first gear movable between a first position and a second position where reverse rotational power of the first roller is transmitted to the second roller. When a controller determines that an upstream edge of the sheet in a conveying direction has reached a third position located between the recording portion and the sensor portion, the controller starts driving the second motor to move the first gear from the first position to the second position and thereafter controls the first motor to perform a forward rotation and a reverse rotation alternately a set number of times.
