PROBLEM TO BE SOLVED: To provide a sheet feeder and an image formation device that can reduce occurrence of a defect in feeding a sheet without reference to the kind of sheets to be fed.SOLUTION: Air blowing amounts of floating means 30a and separating means 30b are varied to find proper air blowing amounts of the floating means 30a and separating means 30b at which the number of times of conveyance in which a sheet flaps is the largest. Then a CPU 211 after finding the proper air blowing amounts controls the floating means 30a and separating means 30b so that the air blowing amounts reach the proper air blowing amount.SELECTED DRAWING: Figure 2 |
