摘要:
A transfer apparatus comprises a toner image supporting body and a corona transfer means, which are oppositely disposed, and a vibrating unit for exerting vibration force to the rear face of a toner supporting body, disposed opposite to the corona transfer means, wherein the vibrating unit has a cantilever structure for holding an end of a piezoelectric bimorph element in which a pair of piezoelectric bodies each having an electrode, are bonded to both sides of a conductive elastic member (a shim member). A protrusion portion is provided on the other end of the piezoelectric bimorph element.
