A conveyor ( ) feeds batches of plastic chips ( ) in feeding amounts W to a charging device ( ). After the plastic chips ( ) have been stirred and charged inside the charging device ( ) for a certain period of time T, they are ejected in batches and fed continuously by a screw feeder ( ) to a drum electrode ( ) at a feeding amount per unit time W . The feeding amount per unit time W is adjusted so as to satisfy W /T≦W ≦v×B×H×D where v is the rotation speed of the drum electrode ( ), B is a width of the drum electrode ( ), H is an average thickness of the plastic chips ( ) that have been fed onto the drum electrode ( ), and D is a bulk density of the plastic chips ( ).
