摘要： An improved interlayer is provided for use in a photoconductor element between an electrically conductive layer and a charge generation layer of the type where a dye is aggregated in a matrix polymer. The interlayer is a mixture of at least one polyester and at least one polycarbonate. The interlayer provides excellent adhesion between the conductive layer and the charge generation layer and dampens any stress to which the photoconductive element is subjected. Minimal effect on photosensitivity is achieved by optimizing interlayer thickness.
