ABSTRACT:
A cleaning unit for removing toner remaining on the surface of the image carrier of an image-forming apparatus is disclosed. The cleaning unit includes a vibration member, a blade member, and a driving part. The vibration member extends in the direction of the width of the image carrier, and has at least one vibration application part attached thereto. The blade member is attached to at least the end region of the vibration member, extending in the direction of the width of the image carrier. The driving part drives at least one vibration application part at a driving frequency that is a resonance frequency. The vibration member provides vibration to the blade member and a force to press the blade member against the image carrier.
