摘要： A sheet feeding apparatus detects the position of a sheet (30) during feeding thereof and calculates a deviation of the detected sheet position relative to a reference position to thereby enable accurate color printing. A follower roller (41) for detecting a feeding amount of the sheet is in contact with the sheet which is fed by a sheet feeding roller 1, so that is rotated in accordance with the movement of the sheet. A sensor (43) generates an output signal each time the follower roller (41) rotates a predetermined angle of rotation. In one form of the invention, a timing deviation detector (51) is provided for detecting a deviation in the output timing of an output signal of the sensor relative to a reference value. In another form, a rotation angle deviation detector is provided for detecting a deviation in the rotation angle of the sheet feeding roller relative to a reference value each time the sensor generates an output signal. A feeding amount deviation calculator (52) periodically calculates a deviation in the amount of feeding of the sheet relative to a reference feeding amount based on the deviation in the output timing of the sensor output signal of based on the deviation in the rotation angle of the sheet feeding roller each time the follower roller rotates a predetermined rotation angle.
