ABSTRACT:
For the enhancement of toner release from an imaging surface on a flexible belt member in an electrophotographic device a resonator suitable for generating vibratory energy is arranged in line contact with the back side of the belt member, to uniformly apply vibratory energy to the member. The resonator includes a horn divided into a linear array of segments, and an array of vibration producing elements, each coupled to at least one horn segment, and driven with a voltage to produce a high frequency vibratory response. To avoid the problem of variations in response that occurs due to varying resonant frequencies of each horn element, the vibration producing elements are driven across a range of frequencies that includes each resonant frequency required, over a relatively short period of time.
