An apparatus for enhancing toner release from an image bearing member moving in a process direction in an electrostatographic printing machine, including a resonator suitable for generating vibratory energy arranged in line contact with the back side of the image bearing member for uniformly applying vibratory energy to the image bearing member. The resonator includes a piezoelectric transducer and a waveguide member coupled to the transducer for directing high frequency vibratory energy to the image bearing member, the waveguide member being divided along a longitudinal axis of the resonator, forming a plurality of waveguide segments with each waveguide segment being separated by a segmentation slot, the segmentation slot having an orientation generally non-perpendicular to the longitudinal axis of the resonator.
