摘要:
A method for recycling photoconductors is disclosed. In this method, the charge transport layer is selectively removed from the photoconductor without adversely affecting the electrical properties of the charge generating layer. The recycled drum may then be recoated with a new charge transport layer and reused in an electrophotographic process. In this method, the photoconductor to be recycled is placed in a specifically selected solvent, such as a dibasic ester, and is subjected to ultrasonic energy, preferably for a period not to exceed about 15 minutes.
