Abstract
An electrophotographic device of the type including a flexible belt charge retentive member, driven along an endless path through a series of processing stations that create a latent image on the charge retentive surface, develop the image with toner, and bring a sheet of paper or other transfer member into intimate contact with the charge retentive surface at a transfer station for electrostatic transfer of toner from the charge retentive surface to the sheet. For the enhancement of toner release from a surface at any of the processing stations, a resonator suitable for generating vibratory energy is arranged in line contact with the back side of the charge retentive surface, to uniformly apply vibratory energy to the charge retentive member. The resonator includes a horn, a continuous support member, and a continuous vibration producing member that drives the horn at a resonant frequency to apply vibratoy energy to the belt. The horn includes a platform or base portion, a horn portion extending therefrom, and having a contacting tip. The horn is segmented, through the contacting tip to the platform portion, into a plurality of elements which each act more or less individually. In…
