ABSTRACT:
A cylindrical and rotatable resonating assembly, generally for use in electrostatographic applications. The resonating assembly is preferably positioned along a longitudinal axis generally transverse to the process direction of movement of a toner bearing member, for applying uniform vibratory energy thereto. The cylindrical form of the resonating assembly allows for rotation of the assembly while remaining in contact with the image bearing member to reduce frictional forces between a contact surface of the resonating assembly and the image bearing member which, in turn, reduces wear of the resonating assembly as well as the image bearing member. The resonating assembly may include a plurality of discrete individual resonator elements, each including a vibratory energy producing segment, such as a piezoelectric transducer, for generating vibratory energy and a waveguide segment coupled to the vibratory energy producing segment for transporting the vibratory energy from the transducer to the image bearing member.
