ABSTRACT:
A development system which uses a donor roll structure including a piezoelectric layer or film for liberating toner particles from its surface. The donor roll is provided with a plurality of electrodes spaced about a circumference of the roll. An electrical bias is used to apply a voltage to electrodes as they pass through a developer nip or zone intermediate the donor roll and an imaging member containing latent electrostatic images. The voltage is applied to each electrode and another continuous electrode which together sandwich the piezoelectric layer therebetween such that a voltage is applied across a portion of the piezoelectric layer in the nip thereby causing acoustic excitation of the portion of the layer only in the nip.
