    Abstract: PROBLEM TO BE SOLVED: To provide a bias charging unit using a bias charging roller with means to reduce contamination and wearing of the bias charging roller and a photoreceptor, in contrast to the prior art where contact of the photoreceptor with the bias charging roller contaminated by a toner/additive causes wearing of both the bias charging roller and the photoreceptor.SOLUTION: A piezoelectric transducer (PZT) 30 is attached to a bias charging roller 26. While a high voltage is applied with a high voltage power supply (HVPS) 28, the piezoelectric transducer (PZT) 30 is pulsed at a predetermined frequency and brought into contact with a photosensitive surface 12 of a photoreceptor 10.
