A multilayer photoconductive element containing a photoconductive insulating composition and a conducting layer, such element having in association with the photoconductive composition an amorphous, water-insoluble polyester selected from the group consisting of(a) polyesters prepared from units derived from at least one aromatic dicarboxylic acid component and at least one diol component, at least one of said acid or diol components being a non-linear monomer selected from the group consisting of an isophthalic acid component or a branched-chain alkylene diol having the formulaHO--CH.sub.2 --R.sup.1 --CH.sub.2 --OHwherein R.sup.1 is a branched-chain alkylene group, and(b) polyester copolymers prepared from units derived from at least one aromatic dicarboxylic acid component and at least one diol component, at least one of said acid or said diol components being a mixture of at least two different acids or two different diols, respectively, so that a copolyester is obtained, and at least one of said acid or one of said diol components being selected from the group consisting of a non-linear monomer as defined above or a cycloaliphatic diol; with the proviso that when said polyester is incorporated directly in said photoconductive insulating composition, said polyester constitutes a minor amount thereof.
