Abstract
An organic photoreceptor ("OPR") including a barrier layer formed from a barrier layer coating composition including a cellulosic resin, methylvinyl ether/maleic anhydride copolymer, a polyamide, a crosslinker, and a combination thereof, provides sufficient protection to the organic photoreceptor from damage due to corona-induced charge injection; is substantially inert with respect to the organic photoconductive layer; exhibits sufficient resiliency to withstand shear, compressional and tensional forces exerted on the belt as it passes through an electrophotographic system when the photoreceptor is used in an endless belt form; and provides sufficient protection to limit or prevent a liquid toner from contacting the organic photoconductor that may result in crazing and/or cracking of the organic photoreceptor during use.
