In the preparation of xerographic photoreceptors it is advan-tageous to direct and control the physical form of the photo-reactive species. There is described a method for localizing in a polymer matrix deposits of selenium and tellurium as well as their mixtures, compounds and heavy metal salts. Generally, the method involves localizing ions of the components of a precipitation reaction in an ion exchange resin, removing all mobile ions by washing and then carrying out the precipitation at or near the ion binding site within the polymer matrix by addition of a suitable second reagent.
