Multilayered photoreceptors contain a charge generator layer and a charge transport layer. Charge generator layer coating formulations composed of selenium dispersions in solutions of neutral andlor acidic polymers emit noxious odors that are especially unpleasant when the coatings are dried at elevated temperatures. One of the polymer solvent systems that givesoff some of the most noxious odors when used to mill elemental selenium into dispersions is phenoxy dissolved in blends of acetone and cyclohexanone. The odors given off are similar to those for sulfur compounds.
