摘要：
An electrophotographic element comprising a high mobility charge transport layer. The layer binder is a polyester according to formula I: ##STR1## wherein Ar represents phenylene, terephthoyl, isophthoyl, 5-t-butyl-1,3-phenylene and phenylene indane; D represents alkyl, linear or branched, or cycloalkyl, having from 4 to about 12 carbons; R.sup.1, R.sup.2, R.sup.7, and R.sup.8 represent H, alkyl having 1 to 4 carbon atoms, cyclohexyl, norbornyl, phenylindanyl, perfluoralkyl having 1 to 4 carbon atoms, .alpha., .alpha.-dihydrofluoroalkyl having 1 to 4 carbon atoms, and .alpha.,.alpha.,.omega.-hydrofluoroalkyl having 1 to 4 carbon atoms; and R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.9, R.sup.10, R.sup.11, and R.sup.12 represent, H, halo and alkyl having from 1 to about 6 carbons; x is from 0 to 0.8; and y is from 0 to 1.
